Repair stripped screw holes in fiberglass
A couple of the mounting screws for the ingress handle on my NL are stripped. If this were wood, I'd glue a toothpick in there and move on. What is the best approach for stripped fiberglass?

Fiberglass construction usually makes use of backing plates when they want to attach something with screws or bolts that will have a lot of pull out force on it. Foam core construction uses epoxy plugs between the two fiberglass layers for attaching things where the force is more in shear.
If there is no access behind where the screws goes just through fiberglass and there is no backing material, then the most common approach is to use the screws to hold and locate the part until a high strength polyurethane adhesive cures (SikaFlex or 3M). Tensile strengths are in the range of 170 to 500 psi. It is what attaches the access ladder to the roof on my TC, the screws aren't really doing anything.
