Dry/Porous Fiberglass

[64studeavanti]

Working on R5423. I have removed the undercoating. In some spots, the fiberglass is very dry/porous and somewhat brittle. 

Any ideas on how to remedy?

I have used penetrating expoxes, such as those from West systems, on plywood before. Should I do something similar? Leave it alone and coat with epoxy primer?

I plan on reapplying the rubberized undercoat, 3M Dynatron Dyna-Pro, similar to the factory, to protect the fenders and other parts of the underbody from rocks etc.

Any ideas welcome.

thanks

I believe your idea of reapplying a quality rubberized undercoat is ideal.

I don’t think trying to seal the fiberglass underbody with any type of resin would be worth the effort… Good luck!

I'd check on some boat forums since they often deal with fiberglass. But I'd think resin or penetrating epoxy sounds good from an amatuer's standpoint.
