Does vinyl ester stick to epoxy?
Specifically the bonding part. Epoxy will bond to poly or vinyl, but they won’t bond to epoxy. So watch the video (which is part 3) to see he uses vinyl ester resin for the 1708 transom skin. He used epoxy resin to wet the ply, then thickened epoxy to bond the marine ply and to fill the side/bottom voids (part 2).
