Fiberglass Tub - hairline crack-What to do?
Our house is 20 years old and we just noticed a hairline crack in one of our fiberglass tub enclosures. The crack is on the floor of the tub, and is approximately 3" long. We have no idea if water is going anywhere, we can just feel the crack with our fingernail ever so slightly. We have not seen any damages resulting from the crack, but we don't want to wait for trouble.
Can this crack be fixed without it being noticeable?
Thanks for any help!
