Phenomenal results! As Will said, they left me speechless. We couldn't be happier!
We have a lovely old iron kitchen sink, double sink, double washboards, but it had been re-coated a couple of times with epoxy paint and who-knows-what. It was impossible to clean and the coating was peeling off and permanently filthy-looking (attempts to clean it just made it worse).
We met Will at the Home Show in March (and checked the company out on Home Stars as well), and the process seemed like a good fit for us.
Will and Chris were terrific -- the prep work involved in removing the inferior stuff used to coat the sink previously was really tedious and labour-intensive, but they did it properly and took the care needed to get really professional results.
If you're worried about the smell, it doesn't last very long. I'm very sensitive to paint fumes, varnishes etc., and usually can't sleep in a house that's been recently painted, but this product didn't have the same effect. That said, we were able to keep windows and the back door open for extended periods to ventilate.
