Will, on the principle that extra weight is a definite downer and always
think light or lighter, I would remove as much as you can without
damaging the fibreglass, subject to getting your perfect profile. If the
gel coat was properly applied in the first place it should be pretty
much in chemical continuity with the FG resin.
Regards, David Joyce, GXSDJ, with gel coat finish I would not change if
you paid me!

William,It should be fine just scuffed. Epoxy will stick to polyester gel c
oat, but polyester won't stick to epoxy,I think the gel coat is epoxy=C2-
anyway.Graham

Will, as far as the factory gel coat goes two very important principles:
1. Make sure you wash all the gel coated bits very, very thoroughly. The
release agent used in the moulds has a great ability to induce
potentially serious allergic reactions, if you just sand it off. (That
speaking with my medical hat on!)
2. You need to fine sand the gel coat until you cannot see even a hint
of any shiny patch, even with a magnifying glass. Any shiny bits however
small will give imperfect adhesion of your covering coat.
