There is a product called "Tough As Tile", a 2-part epoxy system that will work on your sink. I bought some at my local bLowes and am going to try it on my AS tub this spring. http://www.antiquehardware.com/product/70033779/ (it cost about $20 at Lowes). I'd like to see before and after pics if you do the sink :) -Tracey
