: I have an Endeavor with a cut in the bottom. I wish to remove the varnish to
: reach clean epoxy, add a kevlar bottom, and smooth it over with epoxy
: pigmented with graphite. My question is how best to reach the clean epoxy
: without either trashing the topsides and cutting in to the fiberglass? I
: am thinking that I should mask off the areas that I don't want to
: affect,and use a chemical stripper of some sort, assuming that it doesn't
: attack the epoxy. Do I need to run this one by WEST?

That would seem best. Most paint strippers contain methylene chloride, which will attack cured epoxy. With a sweet pungent odor, once you smell it you never forget it. And it is carcinogenic.

Heat is a mortal enemy of epoxy too, leading to possible delamination and bond failure. Stay from the heat gun.

Seems like the only logical safe method left would be sanding or scraping, being careful not to sand through the glass.
