Just installed a SS sink yesterday for a friend of mine. It was a Sterling, made by Kohler. Right in their directions they say to use silicone sealer. I did, and it wasn't a problem. As far as it being an adhesive and not being able to get the sink out later, take the clamps off from underneath, slide a razor knife under the edge and it will come right out.
How do you get a razor knife under the back up against the splash, mike? You are right with the razor, though. It seems to me that the correct sealant would be non-hardeneing Butyl, though, not silicone.
