Hello all, I would like to re-porcelain my kitchen sink. Double basin with integral backsplash for wall mount faucet. Porcelain is worn at the drain holes, pitting around the bottom of bowls and worn center divider rail. Otherwise it is perfect. Problem is I cannot find anyone who can do this (Southern Calif.) The question may have been posed before but any merits to powdercoating a cast iron kitchen sink? I've read its a similar process as porcelain but the firing temp is around 400-500 degrees rather than 1350-1400 degrees. Result is surface is not as hard as porcelain but better than epoxy reglazing. Just wondering, are there other applications / methods that use a high firing finish? Btw, the sink is not installed and can be transported. Any comments / suggestions appreciated.
