I’m working on the PB400's silver paint. So I put on the clear coat. First two, three layers go just fine. Then suddenly, the last layer starts getting mottled spots and cloudiness in spots, not to mention runny. I’m gonna need a bit of help, y’all.

So...not sure what to do. I’ve got 2000 grit sandpaper on hand, but Google has not really inspired confidence in me on what to do if I’m trying to fix the clear coat.

Essentially, I want to remove the top layer and then buff/polish any other inconsistencies, if at all possible. And I’d like to know what tools I’m going to need.
