You'll get several answers. I would suggest putting marine tex into the holes to fill them just below the surface and coat the repair with a dab of gelcoat. Others will suggest filling with epoxy others will say polyester resin. If you use marine tex or polyester resin you won't have to worry about the product degrading in sunlight like epoxy will if not protected from Uv Rays. If you want to fill them temporarily until you're ready to do them all at once you can put some 3M 4200 in the hole then drill it out just prior to repair. Don't use silicone.
