Hi Trevor,

I can highly reccomend Norglass that is what was used on "Altered", it was recommended to me by Tim Heaney ex mossie sailor pro wooden boatbuilder who sprayed it for me, a truly beautiful finish, your not allowed to use Botany Blue though . In fact Tim H is about to use Norglass on the Sabre dinghy he is building, it was also used on his timber Mossie "Merlin" I think.

I have used Epoxy resin brushed on to ply to seal it in the past, takes some sanding afterwards though to get it ready for sprayed epoxy undercoat. Everdure sounds like it could be better.

Regards Gary.
