Although I'm embarrassed to post this pic, since I did everything wrong, it seems, I need help! :0
Meanwhile I know I'm in for a lot of sanding. But can any of this mess be saved? It's a catalyzed (2-part) urethane from POR15 called "Hardnose" or "Whitecote".
I'm saving up for a decent spray gun which was part of the problem, I could see the atomization was not good but plowed ahead anyway... There are runs in multiple places, heavy orange peel, and worst of all, little holes (fisheyes?) right through to the primer, mostly on the left front fender and the roof. They are not as visible in this door pic but you can see the other problems all right. Did I not get the surface clean enough?
I was prepared to sand the runs and orange peel, then re-coat, but I don't know what to do about the pinholes. Can I use glazing putty to fill them, or do I need to sand right down to the primer and start over with the paint?
