What is Interprotect but an
epoxy layer? It sounds like whatever
epoxy was put on your hull simply doesn''t have a fancy marketing name. Despite fancy names and advertising,
epoxy (like gasoline) is
epoxy. If you''ve got a layer of it, it doesn''t matter who made it. If there aren''t any blisters now in a 1981 boat, it sounds like you''re trying to fix a problem you don''t have. Get some new sails instead, you''ll have more fun.
