I have a small gauge (about penny size) towards the bottom of a fiberglass tub/shower combo insert in the house i bought. The rest of the insert is in great condition, so really don't want to replace and am wondering about best way to repair. The previous owner made a very pathetic attempt as you can see... I have used rustoleum tub and tile epoxy paint before and am thinking that tinting that to match the off-white shower will work as the final step, but would like to fill the hole with something first and i'm not sure what. thank you!
