Hi all, I"ve acquired a cedar strip canoe of 40 something vintage, that is a sought after, locally made canoe. The canoe is great shape in the interior, but the exterior has these whitish areas on it. Is this the varnish or is it in need of a new coat of resin? The worst spot is the one where the cloth has been torn and exposed wood, which has since turned gray. I know I can bleach the wood, but for now I am just wanting to get it in the water to use it this summer. Can I put a patch of cloth over the bare spot, and then new resin? Also, how do I tell whether it is epoxy resin or polyester? I plan to next strip the fiberglass cloth off of it within the next year or so, and apply new cloth and resin.
