1. Drill and Reinforce the Fiberglass
Drill a 1/4-inch hole at each end of the crack. Spray high-density foam insulation through the holes if the tub requires reinforcement behind it. When the foam begins to overflow from the hole, stop spraying and wait for it to set before cutting off the excess with a utility knife.
2. Add the Filler
Spread epoxy filler evenly inside the hole and overfill the area with it so you have something to sand down. The patch should be about 1/16 inch above the tub's surface. When you're finished filling and leveling, let the epoxy cure completely as directed.
3. Smoothen the Area by Sanding
Using 400-grit wet/dry sandpaper, sand the repair so that it's as flat as possible. When you're finished, smoothen the area with a 600-grit wet/dry sandpaper.
