I am having a problem with spraying a dyed shellac. The finish looks like it has fish eye. But I can't think of any possible contamination . I milled down some soft white pine. I sanded it to 180 and vacuumed the surface. I sprayed two coats of 1 1/2 lb sealcoat shellac. To tint the wood I mixed some fresh flakes to about a 1 lb cut. I added Transtint liquid dye. I used the same gun and settings as I used with the clear sealcoat. It is an Acuspray HVLP conversion gun using about 5 pounds pressure. I tried a reduced spray volume, then an increased pressure. Not much difference. Anyone have any other ideas I might try?
