When we had to study the problem... we had a larger commercial sink actually two to do. I called some coating experts and they said if its to be inside a sink with lots of water on it they only would recommended polyaspartic coating.  These commercial sinks we did about 3.5 years ago still look good, We see them all the time. They have different people cleaning them so telling the couple of cleaning staff how to best clean them was out the window. So we are proud of how they still look. Below is one that we did. This was sanded with a 30 metal and then coated twice. The hardness is only about a 3 on the mohs scale.

Randy,

That looks nice. How does the polyaspartic hold up over time? Any scratches or chips?

I'm looking for tips and guidance on how to restore marble vanity bowls. They have light etching that needs to be resolved. My main concern is simply working with the concave surface.
