Common Car Paint Problems And How To Repair And Prevent Them

No matter where you drive, nicks and scratches are bound to cause blemishes on your car's paint over the years. Car paint problems are usually caused by normal wear and tear, but sometimes there are distinct reasons why damage occurs.

To preserve the quality and gloss of your car, you should repair any glitches in the paint, as they can easily turn into rust. Here is a look at two common car paint problems you could face, their causes and how you can repair them.

Chemical staining

If you notice any irregularly shaped etching or staining on your car's paint film, chances are it has been damaged by corrosive solvents such as those found in road tar, acid rain or tree sap. To avoid any permanent damage, wash off any such contaminants with water and detergent or with baking soda as soon as possible.

The longer the contaminants stay put, the more damage will occur on the paint's surface. Should washing not suffice, try scrubbing off the damaged layer of paint with sandpaper before applying car polish to restore the lost gloss. In the case that the damage is too extensive, you may need to take your car to an auto body shop for refinishing.

The best way to protect your car from chemical etching is to avoid parking below trees where it could be contaminated by bird droppings or tree sap, and to always wash any foreign materials from the car's body as soon as you can. An acrylic urethane basecoat could also be applied to the entire body of the car for added protection against chemical damage and harmful UV rays.

Air entrapment

Air bubbles can easily get entrapped beneath your car paint film while it is still wet, resulting in tiny unsightly crater-like openings on the surface. Low air pressure while spraying paint on the car or improper setup of your spray gun may cause this problem. The best way to repair such blemishes is to sand the affected area with sandpaper, preferably a type with fine grit, then compound and apply car polish to the sanded area so as to restore the lost gloss.

To prevent air entrapment, it is better to leave car painting to the pros, as they are more familiar with the required speed and distance required to correctly spray paint onto cars. They are also familiar with the proper nozzles and air caps needed to apply clear coatings on different car models. Contact a local auto repair shop for help.
