I say go for it and if there are issues, cross that bridge when you get to it. Sure people will discourage you along the way, but I know people have done a lot worse and LEO now.
I have a Tikka with a stainless barrel, and want to cover the barrel, and make it camo if possible. I saw some camp wrap one time for this purpose, but haven't seen any since.
I have a Kershaw Blur with a black blade. It is the snap-on model. I understand why you want the Benchmade, the quality is better and the axis lock... Get a Benchmade instead.
