claw foot tub in great shape except drain
I was fortunate to be given a claw foot tub that is in mostly excellent condition. Only problem is rust around the drain. I know I could have the tub refinished but would prefer to keep the original porcelain as it is in great condition except at the drain. Is there a product available that could be used to just cover up the drain hole beyond where the trim ring extends or another product made for this purpose? Is it possible to just refinish the drain area without doing the whole tub?
