Default Gel coat removal - water sanding vs. straight line sanding

I have seen several examples where someone attempted to remove only
the "bad gelcoat" layer. In a year or two it looked terrible!


Oh, yes, *the devil is in the details, isn't it.

There are degrees of bad. *If the bad is cosmetic, i.e., scratches and
oxidation, a removal of the surface and reapplication of a compatible (ah,
more details that can be the devil) new layer will look fine.

I can't imagine a reason to remove all of the gelcoat off of anything.

This is a case where working with someone that can teach the ins and outs of
fiberglass work can be invaluable, or valuable enough to save many man-hours
and material bucks.

You mentioned, " I can't imagine a reason to remove all of the gelcoat
off of anything."

and then in a following post,

" If there is degradation of the gelcoat to fiberglass/carbon fiber/
Kevlar
bonding, then the detail is the devil. Nothing to do but to take it
all
off."

I was addressing your first dictum.
