Kohler cast iron sink owners please respond
We have now gone through two Whitehaven sinks (neither of which were installed) and both have areas of missing enamel where you can see black or brown dots of the iron showing through. Kohler insists this is uncommon and these areas will rust. This frightens me! We now have to order a third sink. Have any of you dealt with this. I'm including a blurry photo of the type of thing I've mentioned. Thanks.
