Hello Bob;
My marble bath tub has a hairline crack in the bottom it, and i've tried to find some one who seals marble cracks, but they just want to sell me a new tub. This tub is like new plus I couldn't afford another tub.I live in the lng beach california area. it seems that I will have to repair it myself. Could you please tell me what type of sealant to buy that would seal a marble tub leak?
