I have recently acquired the craft of my dreams, (only 22 years waiting to get me one of these) Peterborough canoe from 1942. Upon aquiring it, it was apparent the exterior hull varnish was loose in spots and indeed even bubbled up in places, here and there. During the 2 day drive back home with it on top of my car, much of the varnish had blown off in the wind! Very little work in stripping needed as apparently there was superficial, if any, adhesion between varnish and planks. Common sense tells me this single topcoat was not compatible with what ever treatment was put on the wood. Anyone have any idea what might have been applied to the hull prior to this topcoat? If so, what would you recommend removing it with? Having spent some time years ago with car paints, I am immediately thinking of the product known as "Pre-Kleeno", but I wonder if they even make that anymore. Insights anyone?
