I think ( could be wrong) my issue was using filler( Bondo) on spider cracks. It was a black hood, after a couple weeks I could see a faint outline of the repair. But for a first time painting it was decent. Should of blocked more and I never got around to cut and buff. It was a single stage black like factory. Will Likely do the same on this one. It's s 88 top that was a factory 1c black that was painted white..
