I've sprayed toners made with shellac + Transtint dyes many times w/o undue problems. However, on my latest project the sprayed film wants to separate, for lack of a better word, into little circles with less toner in the center and more around the edges. It's not fisheyes and I can't see any change in film thickness at the center. The finish looks like what happens when a light rain shower hits the hood or roof of a dusty car. It doesn't happen with the first coat, but does with subsequent coats. I can minimize it by spraying coats of minimal coverage, but I can't really eliminate it. No oil/water in the air, fresh can of amber shellac and new gallon of DNA. I know, shellac in the can has wax in it, but I've used the same stuff at least half a dozen times before w/o this happening. Any ideas?
Thanks,
John
