I am painting the hood on my 99 vette. I had to fix a small spot. When I finished the spot I wet sanded the hood with 400, cleaned it with some wax and grease remover and waited a 1/2 hour, and then sprayed epoxy over the whole hood, a thin coat. I waited 2 days and put ppg black base coat over that. I waited another day and I noticed a spot that had checked, not the area I fixed. I sanded it with 600 wet after the paint was gone I noticed the epoxy was balling up on the paper. I was able to scrape the epoxy off with my finger nail. Any ideas what could have cause this and am I going to have to remove the rest of the paint, it seems to be fine. The only thing I can think of is I used activator that was opened about a moth and a half ago. But I had asked in another thread and was told that would be fine.
