You need to know what hte paddle was originally finished with. If it was an oil-based finish, epoxy will never stick to it and you have to use another oil based finish on it. If it was an epoxy-based finish, then youre good to go with a new epoxy. I know Superior uses epoxy, it states it on thier website. THere are ways to test what kind of finish it is, but im not well versed in that.

: I wonder if people cover store bought wooden paddles with epoxy or
: epoxy/glass?

: I have a couple light wood paddles that came finished with what looks like
: mere varnish. Stored inside the varnish shell lasts forefer except for
: where the paddle gets dings, which open up pretty quickly into soft spots
: if they get wet before repair of the finish. I soaked with linseed oil,
: which stopped the ongoing softening, but this is probably not the way to
: go. Also Linseed oil seems to support mold in a non-bone dry garage over
: time.
