Hello Ian,
My favourite hobby is sailing (Motorcycling and Dukes second I'm afraid) and If I were you I would enquire at a chandlers or a boat building yard especially ones that specialize in GRP (Glass Reinforced Plastic) not wood.
When
GRP yachts are constructed and some wooden boats are sheathed with a glass fibre skin (GRP) a
resin is used, this is usually a clear resin which is applied during what I think is called "Lay Up" numerous layers of glass fibre, much like carbon are laid and resin applied, I know that it is extremely important at this stage to ensure there are no air bubbles or voids as when the resin cures the air bubbles or blisters will be permanent. I believe the final stage is a
Gel Coat followed by a primer and several coats of anti-fouling paint. A resin is what you need and I'm sure they will be able to help.
Another alternative are fishing rod manufacturers, most mordern fishing rods are made from carbon fibre or carbon fibre with kevlar weave, I know this as I'm also a fisherman, although I have not been for sometime because of commitments I have a few carbon fibre rods sitting in my loft collecting dust.
Good Luck and hope this helps.
