When chemically stripping a mid year Corvette, what is the best cure for a small area of fiberglass hair separation? Not major, just a small area on the back. Thanks, Rex

Re: Chemical paint removal
Rex, please elaborate...Do you think the degraded area was DUE to the stripping?...Or, did you just uncover it with the stripping? Sound fiberglass should be unaffected by the stripper, but typically you do not strip all the way to bare fiberglass...the factory primer is sanded off.
The degraded area will have to be repaired; either with gelcoat if it's shallow, or resin/mat if you have to grind deeper to get it all out. -

Probably got into some previous repair. Can I just put a little resin + hardener over it?
Thanks,

Re: Chemical paint removal
If the loose fibers are shallow (right on the surface) then brushing on catalyzed resin and sanding it smooth after curing would be my approach. If it appears the area is deficient of resin deep into the panel, I would probably grind down until I found good fiberglass, then laminate resin and mat to rebuild the area back near contour.
After my post, I realized that catalyzed resin would work just as well as gelcoat...gelcoat is essentially polyester resin if I'm not mistaken. You should probably consider using gelcoat if you have a lot of such damage, or contaminated areas that may be questionable for paint. If this is the only area that would benefit from gelcoat, I would just use the resin and resist the urge to gelcoat the entire car.
Of course, you will still have to finish the cured resin just like you would any other surface filler. Once you secure the loose fibers with resin, you can apply a catalyzed glazing putty or body filler if necessary.Comment
