Lots of beautiful guns shown here! But IMHO, most of them have had their value reduced by polishing. However, if that's what you like and you intend to keep and enjoy the gun then who cares? It's your cup of tea. On the other hand, whenever I see a highly polished stainless S&W for sale in a LGS, I never even ask to see it.
I'm a fan and consumer of Mother's Mag Polish, Flitz, Brasso and Ren Wax. I use these products on my guns in various ways. I'm also a fan of "factory finish" on my guns and so whenever these products are applied they are done so with the light touch of an index finger only. And I'd never let one of my guns get too close to a Dremel or a buffer.
