I did my centers 3 times,took me about 4 hrs each time,and each time I clear coated and each time I went to the car wash,just to rinse the car,it would start to blow the paint off,it would take about 2 trips to the car wash before it started happening,will I ever learn? I'm going to do it again soon.
P.S. I have cookie cutters and my center cap looks like it is purple,and WON'T sand off! Thats probally why the paint won't stick good. Annodized I guess.
