We're thinking of keeping the kitchen sink vs getting a new one since it's worked fine for the 15 years we've lived here so far. However, the undercoating is brittle and flakes off in the cabinet. It's cream in color. Where can I find some of this? I'm guessing the undercoating for your car wouldn't be suitable (eg, fumes). Should we just buy a new sink since everything else will be new? One other downside to it is holes are 6" which gives me only 2 options for Delta Diamond Seal faucets in Stainless, neither of which I like.
