All- Thought I would share a thinning formula for spraying Watco brushing lacquer. 50% Acetone 33% Watco 17% Lacquer thinner. This formula lays the material down beautifully and level, and passes the fingernail test in a week or so. I live in California where good lacquers, like Kel-Lac, Sherwin Williams, etc. are outlawed. I've been having a devil of a time buying a decent lacquer.
