Yes, after shaping the board you can paint the
blank then glass it.Spray paint is fine for Polyurethane blanks, but
not EPS foam as the solvents in rattle can spray paint will melt EPS. You can
always use a HVLP gun, a brush or roller, and
acrylic paints.For painting PU blanks a
with rattle can we suggest several light coats of spraypaint, allowing each
coat to dry for about 10 minutes before applying the next
coat.Let the paint totally
cure for a day before fiberglassing or it may run and smear with the
resin.
