Why does your car paint peel, why you need a vehicle repainting job done, and how to fix both problems. We’ll show you in this article, so you never have to look at an imperfect car body again.
Car Paint Peels: What Causes it?Cars get us where we want to be. Well, some places we want to be. I mean, you cannot drive to the Bahamas, except you’re in the Bahamas. I own a convertible, and I absolutely love my baby. I’m sure you love yours too. You wash and wax it faithfully. If there are some scratches on the painted body, you get some touch-up paint to cover it up. All is good until you notice some peels on the car body, now you’re really concerned. You feel betrayed; you take such good care of your car. Why would the paint peel? To under why this happens, you need to know about the different layers that form your car finish.
Layers that Form Your Car FinishYour car’s finish was formed by different layers of coating:
The PrimerThis is also called an undercoat. This is the first coating applied to the surface of your car body. It gets the surface ready for further coatings. It protects the surface and ensures that other coatings stick to the surface of the metal.
The Base CoatThis coating is applied after the primer. It is the main paint. It gives the car it’s characteristic color. The base coat could be metallic, pearlescent, or solid paint.
The Clear CoatThis is a transparent and glossy coating. It is the final coating for your car. This coating helps to protect the car from abrasion and UV rays. Now you know what forms your car finish and how each coating functions to protect the car body. What causes the paint to peel or delaminate?
Why does Delamination occur?This occurs when a layer of coating or all layers of coating stop adhering to the metal surface of the car. This results in the flaking and eventual peeling of the paint. Some factors that contribute to this problem are:
- Improper Preparation of the Painted Surface: This usually occurs if the painting was done properly. It could be a result of the uneven application of one of the coatings. It could also be caused by improper finishing of the metal panel of the car. If any of the aforementioned is the culprit, then after a while the paint may no longer adhere to the surface causing it to peel or delaminate.
- A Break in Paint Seal: A scratch or peel on the car paint can deteriorate to delamination. This is possible because an exposure caused by a chip or scratch on the coatings may allow moisture to get in thereby causing rust formation. This reduces the adhesive strength of the coatings and gives way to delamination. Under some external influence like high-pressure washing, a chip may be totally blown off leaving a larger area exposed for delamination to occur.
