For a structural repair to screw holes, I swear by West Systems Six10 thickened epoxy in a caulk-type tube. It's not cheap, and you have to use it all or buy spare mixing tubes, but you can INJECT the material into the hole where it will fill the void behind the fiberglass. It is sandable within a few hours.
