I've painted my last few poly blanks with MTN water based spray paint. I have had a problem with the paint smearing while laminating and putting in fin boxes. On the last board I did a green fade from nose to tail. I didn't think there was any paint near the boxes at all, but when I was putting in the boxes the resin had green in it and it looks terrible. On the board before I had a problem with the red smearing onto the deck as I did the laps. I think I can help that issue by cleaning the spreader more. Unfortunately that didn't help with the boxes, Any advice? Is there a water based clear I could spray over the color? Thanks for any help.
