Airweight polishing/finishing question

[44Powers]

Hey guys,
I recently aqquired a PC 637 Enhaned Action. I saw some photos where some folks had polished the cylinder/crane and barrel as these parts are stainless. I kinda like the two tone look...
I've seen that some people just hand polish with mothers mag or flitz. This is probably the best way to go right?
Not that I'm too concerned about it, but would polishing the cylinder/crane and the barrel void the factory warranty?

Also... If I wanted to could I get the entire thing Robar NP3
Coated? Or is there an issue because of the steel components and the aluminum frame?

Thanks in advance!

Robar can NP3 coat alloy and stainless. I had a sig 229 NP3 coated. As for the warranty though, S&W may not like it...

I would ask the Robar people.
The finish on the aluminum parts of my 396 appears to be some kind of powder coating.
It has an almost "metal-flake" look to it and where it has chipped you can see how thick it is.
