I am trying to refurbish a mistreated strip kayak. I have no idea of what materials it was built with. It has some areas that have dark stains under the glass. I have gone down to the wood on those spots. The glass came off very easily. In fact that worries me a bit. Other areas have a white haze or worse. I think what ever varish might have once been on it is long gone and I am not sure how much of the resin is left on top of the glass.

I want to do the refurbish correctly, but I don't want to do more work than is prudent. Any thoughts? I guess re-glassing a boat is a whole lot work than building one.

How much epoxy does it take to do a boat on the outside of the hull only--it is 14 feet long 25 inches wide or so and has a totaly flat bottom.
