The stringer and rails were masked and the pigment coats brushed on. I use a mixture of surfboard lam resin and neutral spray gelcoat. 75% resin 25% gelcoat and 3% Wax in Styrene. The gelcoat is designed to cling to vertical surfaces. This helps on the rails to minimise sagging and separation. The gelcoat ups the geltime slightly without having to use higher catalyst percentages. The board was sanded ready for glossing.
