Re: Stus-List installing plastic anchors in fiberglass
Hair dryer trick sounds like good advice.

Most of the screws holding the forward hatch were getting loose and, of course, the reason was wet core underneath. I drilled out all of the screw holes (oversized a bit) and dried the core where necessary using a trick taught to me by my West System guru. Take a suitably sized Tupperware container, remove the top (throw it away), and cut a hole in the bottom the size of a small hair dryer nozzle. Place the hairdryer nozzle into the hole you cut, tape it in place with duct tape, tape the hair dryer contraption in place on the deck over the wet core holes, and let it run for a while (low heat setting will prevent it from overheating). I needed to move the contraption around to dry various holes in my case. Once you’re satisfied the core area is sufficiently dry, you can then repair. What I did differently in this case was, instead of screwing back into cured epoxy (or using plastic anchors), I bought some stainless inserts for machine screws and epoxied them in place. (Yardley product as I recall.) When I was finished, I could unscrew the machine screws to remove the hatch. Because the inserts were epoxied in place and isolated from the core, I didn’t worry much about the seal at the deck after that. It was a lot of extra work (not sure it was worth it), but the forward hatch was solidly connected to the deck and I never had a problem.

Re: Stus-List installing plastic anchors in fiberglass
I drilled mine out a bit, and pushed some thickened epoxy in, and got some SS Helicoils. I put a bit of Tefgel on the 10-24 machine screws, screwed them into the Helicoils, and then pushed that into the hole. They should stay in place if you have the epoxy thickened enough. Worked great.
