Along everything else, I am building a tri-d chessboars from Star Trek, and as I was working on the boards, after taping the clear squares I hit it with white primer. I did that on a rainy day, under a cover, but the wind drove some drops of water on the white squares. I wet sanded the drops out using 400 grit paper, and let it dry before hitting it with another coat of white.
But, now the white paint has fragmented! Previously it was smooth, only the drops of water made bubbles. Now, after sanding, the finish looks like this! The same thing happened with mat finish I put on my Dejaric table, ruining the paintwork..
Can anyone tell me, what may have caused this, and what should be done to prevent this from happening again. I was using cheap spray paints that I have used for ages. This has never happened before. Temperatures were above freezing, and the board and the paint were warm. The board is clear acrylic.
I am hesitant to finish my protonpack, let alone start work on my Boba lid before this is resolved. After hard work, this sucks..
