If you are using the Seal Coat, be careful what type of paint you're using it with. I can't find the pictures anymore, but painted a bait with a mix of Createx, Polytranspar and Wildlife Colors, and it cracked shortly after the clear was applied (with a brush). I contacted CSI, who asked me to send the bait in for inspection after a phone call. The guy told me over the phone that no paint should interact like that with the coating. After they inspected it at CSI, I got a message on the phone telling me that they only recommend using their paint, and they don't really know what happened to the bait at all. I made a post about it, with pictures, my findings and CSI's findings, but I think it was lost late last year with the server problems.
I would recommend using another type of clear, I've only personally used D2T, Dick Nite, and Seal Coat. I would not use the D2T because it cracks, and pulls away from edges. Good thing is that for the price of shipping, the good folks at DN will send you a 2oz. bottle to try for yourself. There might be other, thin, clears to try, I do not have any experience with them at all.
