I wet sanded the paint, polished and set it out in the sun to dry. Unfortunatly I got too much water in the putty and when the sun warmed it up too much I found 3 blisters coming up through the perfect finish. I took my grinder and ground out all my shoddy, shortcut workmanship I had done. My Bad! Took me about 3 extra days to match the paint surface, prime, and repaint black. I missed a run in the corner and sanded with 1200. Now its ready for final cut and polish.
