I had my car repainted a few years ago. The guy who painted the car did a sub par job because parts of the paint have been flaking off and there are some areas where there is overspray or a lack of clear coat applied. Right now I have an area of clear coat that is starting to bubble. I had one "burst" and flake off, exposing the paint under neath. Can any of you recommend a good clear coat to apply? My plan is to wet sand the clear coat to the paint and apply the clear coat in very light layers and sanding between coats.
