I have an extra bathtub reglazing kit. This is a professional industrial grade product. Works with the plastic acrylic tubs or cast iron tubs. Much better than the cheap DIY kits that most people are selling. It is very easy to apply if you have a little experience with an hvlp spray gun. Includes the primer, topcoat with hardener and reducer. Easy to follow directions. Makes an old discolored tub look like new. This includes plenty of material to do a whole tub. Can also be used on sinks. If you also need to do the walls or surround, message me because this probably wouldn’t be enough for that. Fast, free shipping to the lower 48 states.
