Product review (2 stars): Paint Flakes Off after 1 Year
We got a Kohler oil-rubbed bronze (really just black looking) flange with our last sink because I thought it would hold up better being a Kohler and paying a few dollars more.  After 1.5 years the black paint on it is pealing badly.  The warranty is 1 year. (But from what I have seen, no one seems to offer a black disposal flange that the finish doesn't wear quickly/flakes off! )  I'm temped to say, "We can put a man on the moon, but we can't . . ." - you get the point.

BTW - We are very protective of our black granite sink and never put any harsh chemicals down the drain.
