Tks for your reply, Pete.  I'm not looking to strengthen the dacron fiber but to add abrasion resistance.  In our waters unseen slightly submerged rocks can be encountered anytime.  What I want from the epoxy layer is a little more protection than paint alone can provide.  My major concern in this post, however, is how to prevent the epoxy from soaking thru the dacron cloth & adhering to the varnished & auto waxed hull underneath.  I don't want the cloth bonded to the wood hull, since the skin of the canoe needs to independent of the natural wood movement underneath it.
