 Yeah, I mean, I don't think there's an easy fix for a crack in a tub that's physically cracked. I mean, we've repaired shower pans, for example, by using fiberglass repair or a fiberglass repair kit where basically you're applying a rosin and then you're pressing fiberglass sort of into the mix and then putting multiple layers of additional rosin on top of that. But it's not a very attractive finish.
