I used jack nuts on my rod holders to finally keep them in place. The screws were constantly stripping, and I know people here have tried all kinds of repairs including wood strips, starboard, fiberglass, epoxy etc. But the jack nut did the trick, it's made for thin brittle materials, it's invisible when assembled, and should I need to get to the area behind the rod holder they simply unscrew.
I got mine from a local supplier, but this is what I'm talking about

I'm guessing you could also use Nutserts for some applications, but I don't think they would work for thin fiberglass. They would probably split or crack the hold during installation. (But would be great for thin sheet metal and might work for fiberglass. I just don't know. Anyways, Harbor freight sells a nice kit at a reasonable price:
