How to repair hole in a Fiberglass Tub?
Here is an easy way to do it. 1.Cut a round piece of uncorregated cardboard larger than the hole. 2.Put a piece of thread through a hole poked in the middle of the cardboard. 3. Force the cardboard through the hole. 4. Take some epoxy and get the cardboard good and covered and then use the string to hold it in place until dry. Epoxy dries quickly. 5. After it is dry verify the carboard is stuck good, and then cut the string and poke whatever is left back through the hole. 6. If you are lucky enough that this hole is on the floor of the tub, mix up more epoxy and fill the hole. It will float out smooth on top. If not you can use a piece of clear packing tape over the hole and then fill behind the tape in the hole til full. Stick the top down and wait. 7. Use a piece of fine sandpaper to sand the epoxy smooth. 8. Get some appliance epoxy paint of the same color of your tub. The type that looks like a nail polish bottle.
