Waterlogged Fiberglass Dry or Remove ?

Have a few sections of soft fiberglass in the deck to floatation tank junction, about 6-8" in length, where water got behind the gelcoat and was never repaired. The soggy sections are maybe 1-2" in width. Can these sections be dried and relaminated (thinking epoxy and biaxial cloth) or do I need to grind until I get to clean glass and then patch ? It's a 44 y/o O'day, the laminate appears to be rather thin, at most (not counting gelcoat) about 3/16".

Can you post some pictures Is easyer to see what you have and what you are talking about !!

 

If the laminate is thin, you need more anyway. You can dry it out, but will it be clean enough for a good bond? Probably not, so just grind back to good, solid laminate and add the fabric it needs.

 

Pretty much took your advice, PAR. Better safe than sorry and I only want to do this once. I also have added substantially more material than what came out, as another Ospray owner had same issue with his hull so clearly it needs more strengthening.
