I would strip off any polishing bud back to just the paint. You need it to dry properly otherwise it could get very small blisters. Wet and dry it with 1800 grit. Re lacquer it. Let it dry for a few weeks at least.
Not good.....left lip on garden table to help dry , and wind blew dam thing off on to mono-block now have some lovely scratches to fix. The rate im going with this spraying lark Ill be a grand master before I get car on the road
