I know this is a repetitive and much covered topic. I've read all I can find on this subject, including the Tips for Boatbuilders, but I still need some handholding. I have an 8 year old varnished kayak that has had good use, has got plenty of scratches, some down to the glass and the wood, even a small hole in the bow. I'd like to do a complete overhaul, including a thin layer of epoxy everywhere and then coats of varnish. Questions: What is the best sanding strategy for this plan? What grits, etc? How do I know when I've sanded far enough into the epoxy layer to get good epoxy adhesion? Should I remove all deck fittings or just sand around them? I have a fairly standard bungy setup. Any special handling when I refit it? Any other advice?
