Wow so it seems I was right. I onced posted an issue about GM paints peeling and everyone in the forum mocked me for it and said I was wrong. Well on your issue unfortunately you will have to have your car reprimered and repainted. I did have a chip on my hood on my car and I spoke with my body man here and he explained to me that for the GM cars the primer is put on by robotics and is not roughed up when it goes down the line and then electroplated for paint. the paint does not have a rough edge to stick properly and thats what causes the paint to chip. Well I had the whole hood down and he showed my step by step on how they paint cars at his shop. 1st) they stripped down the whole hood to bare metal and then clean the whole surface with a solvent that evaporates quickly so there is no residue or dust on the hood. 2nd) They rough up the whole hood with a light sand paper before primering. 3rd) they primer the whole hood and then rough it up again and reprimer it and rough it then wipe it down for any lose dust before painting. 4th) they painted the hood with the first coat and then rough it up for color sanding (Bright White) it goes through a series of color sanding and then the final coat is applied along with clear coat mixed in the paint for a glossy finish. it looks factory finished and you cant even tell it was even repainted. Not only that it will last 10 times better then factory as long as I take good care of the paint. The only thing he suggested with the rest of the factory paint job is to wash the car with no harsh deteregents such as liquid hand soap and to use maquires car wash and wax the car with only once a year.
