I want to have an old porcelain tub refinished. The yellow pages are clogged with ads, each company I call touts its exclusive process or refinishing material. Does anyone know of a resource to help compare these processes? Or do you have direct experience with a method that worked. I am not interested in doing it myself and dealing with the chemicals, fumes, etc. Searching on the net yielded hundreds of ads again each proclaiming their method the best. Thanks for any advice.
