I have an old double cast iron sink with an enamel finish that is worn off in spots. Does anyone know someone who can remove the old finish and apply new enamel? I don't want it "painted". :( I want it baked on "the old fashioned way"!
How old is your cast iron sink?
Refinishing will not hold a long time, even when there is limited activity in the sink. You won't be happy with it.
I'd replace the sink. Just a little more money, but the result you want. Do it right and do it once.
