Wood/fiberglass can mean different things. Strip built? 'Glass over plywood?
Glassed over wood/canvas?
In any case you'll eat a lot of dirt taking it down to the wood. Unless this boat is something extra special it's not worth doing.
If the existing 'glass/resin is stuck to the wood a vigorous sanding and a couple of coats of epoxy will pretty it up.
For most boats of unknown origin this low cost low effort approach is the way to go.

: I've been asked to take a look at a wood/fiberglass canoe built in the mid
: seventies. I assume that it was made with polyester resin. Is it possible
: to repair and/or recoat this with modern epoxy? Any particular concerns
: about preping the old surface to bond with epoxy? I have not seen the boat
: yet, but it is being described to me as having a "deteriorated"
: fiberglass coat and I'm imagining that it will need to be taken back down
: to the bare wood. Probably more than I want to get into.
