What to use to fill bolt holes in my fiberglass.

[FrankWhoa]

What do you guys use to fill bolt and stripped out screw holes in your fiberglass hull?

I would like to be able to drill and screw back into the same hole.

Or is there something that I can fill the hole with and set the screw in it before it cures.

I'm trying to redo my seat base

Get some Marine Tex: Marine Tex Epoxy

and you might need one of these: Epoxy Syringes

Marine Tex can be sanded, drilled, and is very strong. If the holes are deep you may need a syringe to inject the Marine Tex into the hole. You can't go wrong with this method.
