I've seen professionally refinished tubs that look brand new. The process costs less than removing and replacing existing tubs, but it's still not inexpensive. There are DIY alternatives out there that LOOK like they work, but do they?? I've rounded up a few of the more popular bathtub refinishing kits. Take a look and weigh in to the discussion. Have you DIYed a tub makeover? What product did you use? How's the finish holding up?
