I had heard about this before, but had never used it until today. I used a gray Scotch Brite pad to clean up an old S&W Model 65 that I had recently bought. The gun was in good shape but had a lot of scuffs and fine marks from years of holstering and handling. I was amazed at the results. The gun looks like brand new with a factory satin finish. The pads are very easy to use and not nearly as much effort as polishing compounds. Just buff in the direction of the grain of the steel, generally parallel to the length of the barrel on all surfaces.
