I'm restoring a 1970 something sunfish and I have screw holes in my boat that are shot all the way through. I have filled all of the other holes with epoxy and I'm not sure what to do with these. I think that putting a sheet of fiberglass over the top is a bit excessive but im not sure what my other options are. Theres no wood backing and I can access both sides with a view port. Any ideas of ways to fill them without having resin run through?

Depending on whether these holes are going to be reused (like under the splash guard), thicken the epoxy with a West Systems product or moosh some fiberglass threads into the holes. There's always Thixo ($22).
Inject resin with a disposable syringe, turn the hull upside-down and wait out the cure.

If you can access the underside of the holes put tape over them so the resin can’t run through. Otherwise use thickened epoxy or Marine Tex or Thixo as LV mentions.
