Just practicing some painting on a hatch before doing the whole deck. Im using International Perfections Undercoat. The first coat ended up with lots of tiny bubbles which look like pits when dried. Some advice was to let the pot of paint sit after missing and Internationals technical sheet says leave for 5 minutes. I also sanded out the bubbles where possible with approx. 280 grit.

So for the second coat I left the cup of paint for 10 minutes and there were still microscopic bubbles in the cup. I tried popping them with a paddle pop stick but after applying the second coat the coat is now full of little bubbles as it dries. Any advice would be greatly appreciated.
