PVA can be applied using a brush, cloth, sponge or roller or the part may be dipped in the PVA and drained. A professional quality spray gun is recommended in order to produce a smoother surface on the mold. With practice and good spray equipment, a Class “A” automotive quality finish may be obtained. The use of an HVLP spray gun with about 20 PSI (~1.5 bar) pressure at the gun using a spray tip orifice size of 1.8 – 2.2 mm is recommended.
