I have a fiberglass tub that is pitted and hard to keep clean. The tub was like this when I moved in. I don't know how old it is. I've tried everything short of filling tub with water and adding bleach. Will it be beneficial to refinish it?
If you refinish it, bear in mind that it must set a few days before using again (ask how many days) and that it must be cleaned with something that won't scratch as the new finish is very delicate.
