Hi, Mike. There are porcelain paints available but if you plan to keep the same tub for a while, I think that you should look at another option. There are people that make fiberglass liners for your present tub. They pride themselves that they have molds for about every tub ever made and if they don't have one for yours, they might make you an even better deal on the job. Check this out in your area and see what you think. Start with the phone book.
