The bathtub at my new place isn't in horrible condition, but it does have a few patches on the bottom that look a bit grayer than the rest of the tub, and are rougher. In general the bottom is not as smooth as the sides. We think it is a cast iron bathtub (at least the bottom is all black when we look through an access panel), but we're not sure. There's no rust showing through.
Would it be a good idea to get it refinished now to protect the tub from further damage? Or is a new coat of glazing not significantly protective, in which case maybe we should just wait until we really don't like how it looks before spending the money (especially since the refinished surface won't last that many years either)?

I give mixed reviews to tub refinishing. I have had many tubs and surrounds refinished as opposed to replacing the units. Even though a good refinishing job is not cheap, usually around $300-$400, it certainly is less expensive than the labor involved in removing, framing and installing a new tub and surround. I have found a good sub-contractor for these jobs and the difference between a good long lasting job and a so-so job is in the prep. One sub I used years back did not take the time to really clean, sand and prep the surfaces before spraying the epoxy finish, had some problems and call backs within 2 years. I have a few jobs out there over 5 years old now, with no problems or complaints that my current sub has done, and done well. So I guess the moral of the story is, a refinish job can be a good long lasting solution if done properly with good materials. Side note: Don't wait until the original finish is worn to the cast iron. When rust is present, it makes refinishing more difficult and expensive.
