What are some ways to fix a clear coat peeling off a car?


Quick Answer

While in many cases the only solution for fixing peeling clear coat on cars is by entirely removing and reapplying the clear coat, very small blemishes can be repaired by slightly scuffing the area for adhesion, then reapplying a few layers of clear coat. However, this is only a suitable solution for coin-sized clear coat blemishes.

A coin-sized clear coat blemish can be repaired by reapplying a few layers of clear coat. In order to do so, an area of approximately one inch around the blemish should be scuffed with a fine grit, non-woven pad. After masking the area to be painted, apply two layers of clear coat. Finally, the new clear coat should be blended into the old clear coat to ensure a seamless transition. Keep in mind that this is only a short-term repair.

The reason why large areas with peeled clear coat cannot be easily fixed has to do with the car’s paint. Modern car manufacturers use thermoset paint, meaning that it will not flow once it has dried. The clear coat is applied while the car paint is still slightly wet, which allows for both layers to bind. Fixing a large patch of clear coat means creating a new layer that does not bind with the existing car paint, meaning that the clear coat will be significantly weaker and will fail much faster than the original clear coat.
