![]() There are several reasons this can be fixed, including:ġ) The base coat has had little exposure to the elementsģ) It’s small and out of the way so not likely to be seen. One of them is a perfect example of the type of clear coat issue you can fix. Now Jaded, the pro-touring SEMA show Mustang, has some minor flaws in the clear coat mostly brought on by the frantic pace at which Kevin had to finish the car for the show. Plus, the adhesion is gone, and sanding it to get it back makes it almost impossible to match and blend it to the surrounding areas. Putting clear over the top of it will delay that, but it will still continue to deteriorate under the new clear. The color coat is only to provide color it is not stabilized for UV or exposure to air and contamination, and once it has been, it is only a matter of time before it fails, too. And people ask all the time, why can’t I just put clear coat back on? The problem is the base coat is compromised once it has been exposed to the sun and air. This hood is typical of most cars with delaminating clear coat issues. With that in mind, we’ve put together some clear coat repair tips for DIY users who want to temporarily restore part of their paint job. Clear coat spot repair should primarily be limited to relatively new blemishes in less-seen areas.

(I put wet and dry in quotes because urethanes cure by a chemical process, not by the evaporation of a solvent the way other paints dry.) The new clear coat will never be as strong as the original and will fail much quicker. You can sand for adhesion and spray a new coat of clear over the base, but it will never lock in, and it will always sit on top of the old clear at the edges. The clear coat creates a strong chemical bond with the still slightly “wet” paint and locks in. This means that once they “dry” they won’t flow again. Modern urethane paints are thermoset paints. The bad news is, you can’t just sand for adhesion and respray clear coat. Some cars, like the Plymouth Neon, seemed to have paint and clear coat failing before they were even off lease. ![]() However, many cars from the 80s and 90s have clear coat paint that is just peeling and flaking off in chunks. ![]() ![]() Because drivetrain technology had hit its stride by then, cars like 5.0 Mustangs are still running and driving just fine. That may not seem all that long ago to some of us older guys, but these cars are now 30 years old and entering prime project car territory. Since the 1980s, automotive manufacturers have been painting cars with two-stage base coat/clear coat systems. How to Repair Clear Coat – Kevin Tetz Shows the Best Way to Fix Paint ![]()
