Prestigious Auto Body Paint

In the first part of this common car paint problem series, you were made aware of five of the many hitches your car paint could possibly meet during its painting process or over the time of its usage. In this article, we will bring to your attention more glitches that you can fix yourself and can prevent from occurring, since you are already made aware of them.

Here are the four other possible problems you could face when it comes to your Car Paint in Santa Barbara:



Chemical Etching or Staining

Also known as acid rain, spotting or discoloration, this kind of problem is characterized by irregularly shaped etching, discoloration or pitting that appears on your car’s paint film.

Cause:
When damaging natural contaminants like tree sap, acid raid, road tar and bird droppings, among others, stick to the surface of your car for a long period of time, a chemical change happens and will cause staining or chemical etching.

Repair:
You can mend this kind of blemish by washing your car with hot water and soap, rinsing it and then drying it thoroughly. You can also do some solvent cleaning using the proper surface cleaner. You can also wash your car using a solution of baking soda and water before rinsing it well. The appropriate mixture for this solution is one tablespoon of baking soda dissolved in every quart of water.

If washing will not suffice, you can compound the blemished surface and polish it after so its gloss will be restored. If polishing does not work, you can wet sand the problem area with 1500-2000 grit sandpaper before doing the compounding and polishing process. Should refinishing be needed, you must sand the blemished area with the right sandpaper and wash it with the baking soda solution before you finally refinish. In severe chemical etching cases, you must remove the finish right up to the bare metal of your car’s surface.

Prevention:
Always remove harmful contaminants that can be dissolved by water through regular washing with the use of clear water and detergent. You should also wax or polish your car occasionally. As much as possible, do not park near factories that may releases chemical byproducts into the air. You should also refrain from parking under electrical wires where your car may be subjected to bird droppings or under trees where it may get contaminated with tree sap.

During your car’s refinishing process, it is also best if you will make use of an acrylic urethane basecoat and clearcoat system so your car will be given maximum protection from chemical or natural elements.

It is imperative for you to take note as well that when you are buffing or sanding a basecoat and clearcoat finish, you should see to it that the clearcoat film’s thickness should be at least 2 mils as this helps sustain proper protection against the ultraviolet rays of the sun. Should mending a blemished area result in the removal of more than .5 mils of clearcoat, refinishing is definitely advised.



Cracking

Also termed as alligatoring, checking, crow’s feet, spitting or crazing, this problem usually appears as lines or cracks in your car’s topcoat. Appearing like the cracks on dried mud, these marks usually come in different widths and lengths.

Cause:
There are a number of things that could result in the cracking of your car paint. These include excessive thickness of your undercoat or topcoat’s film, force-drying of undercoats with the air coming your spray gun or inadequate flash time after every coat.

The non-thorough agitation or stirring of the paint ingredients or the improper mixture or excessive usage of hardener are also two other possible reasons. Then, there is also the use of standardized hardeners or reducers or the breaking down of your car’s finish due to the continued exposure of your vehicle to direct sunlight, extreme changes of temperature or moisture.

Repair:
There is nothing else you can do to fix this kind of blemish, but to get rid of all the cracked paint film and then refinish.

Prevention:
Even during the painting process, you can already prevent cracking from happening and it can be started by the proper application of all paint materials according to all the directions on their labels. Before starting with the refinishing procedure, remove all the cracked or crazed finishes completely.

Only use the recommended paint additives and mix these thoroughly with all the other ingredients. Each component must be added according to the recommended sequence and proper ratio for mixing. All materials should be agitated or stirred meticulously as well before using to make sure that all the ingredients are mixed into the solution.

Never use air from your spray gun to force dry undercoating. Be sure to use only the recommender reducer or thinner and hardener and measure them accurately before application. If you want maximum durability and gloss for your car, you should always use a two-component undercoat and topcoat system for it.



Chipping

Also known as stone pecks, nicks, bruises or chips, this kind of car paint problem is represented by damage to the paint film, which leaves a notch, void or nick in the job’s finish.

Cause:
Loss or lack of the paint film’s adhesion to the substrate is what usually brings about this kind of blemish to your car. This is usually due to an impact from such hard objects as stones.

Repair:
Damaged areas should be sanded and feather-edged to get rid of the chips, before it must be refinished.

Prevention:
Areas of your car that are likely to get chipped should be applied with a flex agent in its undercoat or topcoat system and this should be of the top grade two-component quality for maximum protection.



Dust Contamination

These blemishes, which are commonly known as dirt in the car paint’s finish, are actually foreign particles that have been set in in the paint film.

Cause:
There are several reasons behind the dust contamination problem of any car painting job. These include a dirty and dusty environment used for the spraying process, insufficient cleaning of the surface that needs to be painted or improper work or filthy work clothes that may have lint, fibers or dust.

Unfiltered air going inside the spraying booth or poor air filtration, the use of a substandard masking paper or particles coming from depreciating air supply lines are also other probable causes for the problem. If you used an unclean spray gun or you removed your car from the spraying booth even before the paint finish is free from dust, then it is also possible that dust contamination could happen.

Repair:
You can mend dust-contaminated areas of your car paint by sanding it with 1200 grit sandpaper. You can also use one with a finer grit, if you wish. After the blemished areas have been sanded, you can start compounding and then polishing to regain the gloss of your car. Just like with the air entrapment problem, you can actually do the sanding, smoothing and refinishing procedure if you have found dirt in your car’s paint finish.

Prevention:
Keeping your work area and spray equipment clean and free of any foreign particles is the first thing you can do against dust contamination. You should completely blow off around the doors, windows, jambs, moldings, wheel openings, trunk, engine compartment and hood. All the surfaces that need to be painted as well as the masking paper should also be wiped off with the use of a tack rag. Masking materials should all be of high quality or else you might find your paint job contaminated with wicks from newspapers, which tend to break off and blow right into your wet paint.

Appropriate air filters should also be installed in your work area and not the furnace-type filters that are usually used in residences. You should make sure that any leakage in your spray booth due to gaskets, doors, filters or seams that have been poorly fitted are repaired. Faulty air lines must be replaced or repaired as well. You should also make sure to wear a paint suit that is free from lint during the painting process. Unless your car finish is free from dust, you should keep you vehicle in a clean environment.

You should take note of the fact that fine dust particles that may fall on your car’s still tacky surface may be set into the finish, thus creating a mark that may appear the same to solvent pop. This blemish usually happens on vehicles that were removed from the spray booth while it is still tacky and left to dry completely in a different location. You can get rid of this kind of contamination by sanding and then polishing the affected area. However, if the problem is really solvent pop, the finish will have small craters or pinholes right after it has been sanded.

Common Car Paint Problems: Their Causes and How to Repair and Prevent Them from Happening – Part 1

Written by Prestigious Autobody on . Posted in Uncategorized

Car Paint Santa Barbara

Over the years of using your car in and out of Santa Barbara, there are really times when you will notice blemishes appearing on its paint. While others might be because of normal wear and tear, others really have their own distinct causes, which can actually be prevented. Once you notice these marks on your car paint, it is best if you will have it repaired as soon as possible. Take it in to our shop, we cover all Paint in Santa Barbara.

Here are several car paint problems, their causes and how to repair and prevent them and keep you out of an Auto Repair Santa Barbara Shop or Auto Repair Goleta Shop:



Craters or Air Entrapment

This type of blemish is characterized by openings that look like small craters. They can be found in or on the paint film of your car.

Cause:
Air pockets that have been buried or trapped in the car paint film while it is still wet. These usually go towards the surface of the film before bursting to form tiny craters. Usually this air entrapment problem is caused by insufficient atomization and may be because of low air pressure or the improper setup of your spray gun. It could also be caused by the spray gun’s too close distance to the car’s surface while painting or its slow travelling over the panels.

Repair:
Sand the blemished area with a 1200 sand paper. You can also use one with a finer grit if you wish. After sanding, compound and then polish the sanded area to bring back its gloss. You can also use the known procedure of sanding, smoothing and refinishing.

Prevention:
If you are painting your car yourself, you can prevent craters from forming on its paint by maintaining correct distance and speed of your spray gun. You should also use the amount of air pressure that is recommended for the kind of paint and spray gun you are using. You should also follow the recommendations with regards to the proper nozzles, air caps or needles needed for clear coatings.

It is also good to note that several cases of crater formation on car paint may look quite the same to dust contamination or solvent pop. However, air entrapment usually happens with wet film and can be repaired by following the process of compounding. Meanwhile, dust contamination normally appears when the film is already becoming dry. Craters caused by dust usually hold a speck of the offending material right in the middle of the opening. Solvent pop also happens after the skinning over of the film and usually forms pinholes when sanded.



Blistering

These are the swollen areas on the topcoat film of your car paint, which look like bumps, bubbles or pimples. More often than not, you will notice these marks only months after paint has been applied to your vehicle.

Cause:
Blistering is often caused by the confinement of moisture underneath the paint film. This, in turn, is caused by contaminated air lines, inadequate drying time after wet sanding and spraying in places with extremely high humidity.

The use of poor grade reducer or thinner or one that evaporates too fast is also another reason that could cause bumps or bubbles to appear on your car paint. It could also be because of the solvents that have been trapped after the application of wet heavy coatings with insufficient flash time in between coatings. Applying paint over rust, grease or oil and inadequate drying time of undercoats before the application of top-coating are also other reasons for the appearance of this type of blemish.

Repair:
These pimple or bubble blemishes can be repaired through the removal and refinishing of affected areas. In extreme cases though, marked parts should be stripped until you arrive at the bare substrate before you can start with the refinishing process.

Prevention:
If you prefer to do wet sanding, you must allow adequate time for the evaporation of the moisture. You must keep away from wet sanding any lacquer primer surface whenever possible though. Moisture from air lines and your compressor should also be drained frequently. When applying paint during humid conditions, you must add a retarder or allow added flash time in between coatings. If possible, only spray during low humidity weather.

You can also prevent blistering from happening of you will choose the adequate reducer or thinner for spraying conditions. You should also allow undercoating to cure or dry thoroughly before applying the top-coating.

Materials or products should also be applied based on the recommendations posed by the manufacturer and you should also allow the proper flash time before applying another coating. It is also best if you will prep and clean the substrate with the use only of recommended procedures and products.



Bleeding or Discoloration

This is characterized by a yellow or red discoloration that usually appears on the topcoat color of your vehicle.

Cause:
This kind of blemish is often caused by the dissolution of the pigments or soluble dyes in the original finish of your car brought on by the solvent of the new topcoat. Once these pigments dissolve, they seep into the topcoat and cause the discoloration.

Repair:
You can fix this problem by allowing the pigment to cure or by isolating with two component undercoating before refinishing. You can also get rid of the original paint film before starting with the refinishing process.

Prevention:
The best way to prevent discoloration or bleeding from happening, you need to isolate the area you suspect to be bleeding through the application of a sealer or a two-component surface. You should allow this to dry or cure according to the product recommendations, before you can apply the topcoat you want.



Chalking

You can usually see this as a chalky white blemish that appears on the paint film’s surface. This is also known as fading, weathering or oxidation.

Cause:
This kind of flaw on your car paint is largely due to a pigment that is no longer protected or held together by the resin, which results in the lackluster or powder-like appearance of your car’s surface. The reasons for this occurrence are the wrong application of your paint product, the natural wear and tear of your car’s paint film, the excessive utilization of fog or mist coats during the application of single-stage metallic finishes and the use of nonspecific reducers, thinners or hardeners in the paint.

Repair:
You can mend this kind of flaw by using compounding procedures to take away the oxidation and then by polishing so that the gloss will be restored. You can also sand the blemished paint film and then refinish it after.

Prevention:
During the painting process, you can prevent chalking from happening if you will agitate, shake or store all the paint products thoroughly before application. When you are using single-stage metallic finishes, you should apply the fog or mist coats by panel while the finish is not yet dry.

You should be aware that when the clear resin protecting the pigments and flakes of your car finish wears off, these components are exposed to the natural elements, which causes their rapid deterioration. Washing your car once every week and waxing or polishing it occasionally can help in getting rid of weathering from your car’s finish.



Blushing or Milkiness

This is characterized by a milky-gray cloud blemish that can be seen on your car paint’s film surface shortly after or immediately after it has been applied.

Cause:
Air moisture condenses on or in your car’s paint film when you spray during humid weather. This is because the evaporation of the solvent and the air coming from the spray gun lowers the temperature of the substrate right below the standard dew point. Such condition is worsened with the utilization of unbalanced or too fast drying reducer or thinner.

Repair:
If blushing should happen during the car painting process, you can fix this by applying heat to the area where the blemish is or adding a retarder and putting on additional coatings. If your car’s finish has already dried, minor milkiness can be mended through using compounding procedures or polishing. However, more serious blushing will need for you to sand the blemish before you can refinish it.

Prevention:
Blushing or milkiness can be prevented if you will always utilize high quality solvents and reducing or thinning materials based on the directions specified on their labels. You should also make sure to choose the right reducer or thinner for every spraying condition. Only the recommended volume of retarder should be added when you are spraying during humid conditions. You must also apply some heat to your car’s surface after paint application so that excess moisture will evaporate. Remember that as your thinner dissolves, air moisture naturally condenses in your car’s paint film.

The five problems mentioned above are just among the many common glitches you might encounter when it comes to your car paint. The good thing about arming yourself with such information as the ones you have just read is that you will be aware of what caused the problem, the ways you can fix it and how this can be prevented.

9 Easy Steps in Maintaining the Beauty of Your Car Paint

Written by Prestigious Autobody on . Posted in Uncategorized

Polish-b70fcd4d62

Thanks to all of our loyal customers, Prestigious Auto body today is the best Auto Body in Santa Barbara. Here are some tips on maintaining the beauty of your vehicle. It’ our way of saying thanks

More often than not, your choice when it comes to the color of your car is based on how it looked when it was still displayed in the showroom. In the instant when a car’s color catches your eye, you won’t think about how to maintain the newness or beauty of its car paint. You will only think about how it would feel to ride in it and how you would look while riding it.

Your car won’t sparkle as brightly as the first time you set eyes on it, if you won’t take care of it. After several months of use when it has been splashed with mud, covered in grime and pollution, rained and pooped on by some transient birds, it won’t nearly look as appealing as it did when it was still in the showroom.

You have to think twice before choosing a color for your car. You have to consider what you can do to maintain the quality of this color, so it will look like brand new even after years of use.

Below are some easy steps you can observe in choosing the right color for your new vehicle and in maintaining the quality of its car paint:

1. If you are planning on getting a car in metallic or pearl colors, make sure that it has been applied with premium quality car paint. Metallic flake or pearl colors are not easy to match in case of damages caused by accidents. However, if you have a car with paint coming from a top rate company, then you can be assured that you will be able to find the most precise mixes that will match the factory color of your vehicle.

2. Never fall for the smooth talk of salespeople and dealers who will persuade you to avail of products for paint protection. Although they are boasted to maintain the pristine color of your car for its entire lifetime, this is not exactly true. This means you will just be spending for nothing. If your car isn’t brand new and you weren’t able to maintain the color of your car, don’t worry, Prestigious Auto Body has the best Car Paint in Santa Barbara.

3. If you know that you can’t wash your car as regularly as you’d like, then never make the mistake of getting yourself a black car. Compared to white, champagne or silver that are easy to clean, black-colored cars are harder to maintain.

4. It is best to park your vehicle in a covered or sheltered area. If you can avoid it, make sure not to park under power lines or trees. Power lines are favorites for birds that will have the tendency to poop on your car, while trees might drip sap on your beloved auto paint.

5. Unless your car is quite filthy with grime and other pollutants, it is not advised to use detergent or soap in washing your car. If it is necessary to use soap, then make sure to use only small amounts.

6. Should you find bird poop, spattered bugs or sap on your car, you need to remove them immediately. Remember that the longer they stay on your car paint, the harder it is for you to get rid of them. This will lead to a greater probability of your paint being compromised. Plus, bird poop is known to eat into automotive paint if it is not wiped or washed off as soon as possible.

7. It is advisable to wash your car with fresh water as often as you can. You also have to remember that after doing this, you should not drive your car while it is wet. Dry it up first with chamois cloth.

8. If you don’t have a proper garage and you just park your car on the street, you have to remember to wax your car frequently. This is the only way to preserve the luster of your vehicle’s paint job.

9. You will only need to wax your car twice a year if you have a garage to properly house your vehicle when you are not using it. However, you should use a high-quality carnauba wax for the job as this is guaranteed to help preserve the quality of your car paint. Although this kind of wax is not easy to apply, it is difficult to remove and will last for as long as the next time you need to wax your vehicle again.

If you will just have all these steps in mind, you will do great in choosing the right color for your car. Remember that it is not just your vehicle’s color that will tell people the kind of person you are, but also how you take care of it.
