Ive revarnished several boats, some several times some back to bare wood.

The Kayaks ALWAYS look better after the job than they ever looked before.

I have always varnished my boats but painitn will give you better results because you will never see any of the crazing that can accompany a deep scratch.

If you have any deep gouges that you think need re-'glassing just sand them with your finger and course sandpaper until you have made a depression as deep as the gouge. cut some football shaped peices of fiberglass cloth the to fill the depression you made. use larger peices first then smaller as needed to roughly approximate the level of the sorrounding surface. epoxy, sand and skimcoat as you did origionally. then paint or varnish with the rest of the boat.

This technique works great, even on varnished boats

If the damage is really bad you can peice-in some new wood. when you are done, you may be the only one who knows there was a problem.
As : Hi Paul
: What I've done,and it worked great for me, is to sand down any areas of
: damage into the cloth or wood and do the apropriate epoxy repair, then
: give a light sanding to the rest of the hull. Apply a coat of highbuild
: primer and then sand till only the low spots and scratches have the primer
: remaining (the vast majority of your hull should be paint again). Repaint
: and your good to go.
