there arent any dumb questions, just the ones not asked.
I myself hadnt had any problems with my gun having camo, my shotgun has a grey wood finish, hasnt mattered yet. I think it would probly be best if the gun you use does not have a glossy finish. To save movey u can buy some camo gun tape.
If it's going to be a dedicated turkey gun, I suggest spray painting it with Krylon Fusion and being done with it.
1) Fusion prevents rust-- it's like painting lawn furniture
2) Yeah, you can get a $500 finish applied, but then you scratch it up. Spray painting problems can be solved with a $3.00 can of paint.
3) Nothing will ever happen to the finish of your gun.

This is a photoplay of my first try at spraypainting a turkey gun. The important thing to notice is how bad the tape had messed up the finish of the barrel. Yuck!
