answer:What did he use to buff and shine it? I’m wondering if the thing that polishes cars will do it -the thing that spins. As for whether or not I’d do it, my sink is in good shape. I guess a lot would depend on the quality of the sink, the quality of the steel. Also, it would depend on the condition of the countertops. If the countertops are crappy, you may as well just replace the whole thing (tops and sink). If the countertops are in good shape, you’d have to weigh the cost of buffing the sink vs. replacing entire sink.
