Yes, there is a certian paint that they use to refinish a tub. There is a lot of prep work that has to be done (sanding) and the paint is a two part mix that has to be sprayed on to look good. (it's also very toxic to breath) You only have a short time to get the paint down before it starts to harden (it's epoxy). You only get one chance to do it right, if not, you get to start all over again.
