RE: COATING/PAINTING/BALSA/1/2A'S
I use nitrate dope mixed with talcom powder, 2-3 brushed coats then butyrate color. Makes a decent finish. I buy randalphs butyrate and nitrate at about 27 bucks a gallon. If you brush on a coat of nitrate then cover with silkspan followed by a couple more coats of nitrate you can completely cover the wood grain.
