Hi, Joe. you might want to search the board. There are quite a few posts on this subject. Hit ctrl+F and type tub in the block then keep clicking and reading. The bottom line is that many people say that they can just spray on something and it will look great. It will but this will not last long. Your tub has a porcelain finish that requires that the tub be baked in an oven at high temperature that to turn the surface into glass-like porcelain. So obviously this is not a DIY process. Better tub refinishers can spray an epoxy like paint that uses chemicals too toxic for DIYers to handle after surface prep that requires sophisticated equipment. Take a hard look around and you may be lucky enough to find someone that can refinish your tub so that you can expect a refinish job that will last a long time. By the way DIY means "do-it-yourself".
