I use a reuseable wrap on my stainless rifles to reduce glare, it isn't really sticky like a tape, but it sticks to itself. It turned out to have some other benefits as well. I found some at Alberta Tactical Rifle, but I believe I saw some in the bow-hunting aisles at Wholesale Sports as well. Its called Camo Form, made by a company called McNett. Its pretty much a camo'd tensor bandage with a tacky (read slightly sticky) texture. It increases your grip anywhere you apply it, as its got a fabric texture impregnated with latex, a side benefit is that it protects the finish of your firearm. Considering it has a few colors and camo patterns available, you're not tied to what finish you have on your rifle(s). Just mummy up your weapon and head out. I have a roll of both digital desert and snow pattern. It can be a bit of a challenge finding a good way to wrap your rifle, but I didn't get too crazy with it, just wrapping my barrel and forend ahead of the action.

I like it as you can use it on anything you have, the stuff is reuseable, and it the only way it will affect resale of a firearm is by increasing it (less scratches, no permanent paint job that may not appeal to many)
Snow camo your gun?
