I went to repaint my die cast metal engine cover and got all these issues. I think my main mistake was breaching the original paint when I did extra sanding to smooth out some remaining fine raises on the surface. The fresh paint has somehow reacted with the original paint edges I exposed and lifted them, leaving an yucky finish. I got bad orange peeling from heavy coating in one part. If I had just left them after my original light sanding, it would have turned out acceptable. Now I'll have to redo it down the track after it has fully cured.
Ahh, if only victa had kept producing the thumblatch catcher series, they would be in better shape today!
This usually happens when using paints with a different solvent base say an enamel (turps) painted over using a paint that uses a different solvent base such as an acrylic duco, this will cause the frying of the paint such as you have experienced it can be overcome by using an undercoat before applying the new paint, sorry I cannot tell you which is the best to use but your local paint shop should be able to advise you.
I had a similar looking thing happen to one part I sprayed with a pressure pak. I put it down to the paint separating and not being mixed properly before starting, it spat out droplets of solvent first which the rest of the paint wouldn't go near. Since then I shake my cans for the recommended 2 minutes and I have also stopped turning the can upside down and spraying the paint out when I'm done. As for the fix, I just waited for it to dry and gave a few more coats which filled up the holes.
Hi Madmower, as it's not going to be at a show and shine and is hardly seen, I'll just lightly sand it and blow on a couple more coats. It still looks better than it did before.
