The finish issues have to do with the clearcoat that S&W is applying to the 642. Some, including members of this board, have used strong cleaning solvents and have damaged the finish. Apparently S&W is trying to make the finish of the aluminum frame and the finish of the stainless cylinder and barrel match. For some reason, this has involved a clearcoat. I have a 642 and I've shot it a couple hundred times, cleaned it and have had no problems. I usually don't get the powder solvent all over the exterior finish of the gun or maybe what I'm using isn't strong enough, who knows. I like the gun and it's quickly becoming and everywhere gun for me.
