i was using it to wipe a LEUPOLD 12x scope down as well as guns, and noticed the scope tube turned red except under the slip-on scope covers where the sheath never got to. So far I have a S&W 19 that the bbl and cyl have turned; a kimber slide;a citori frame; a ruger m-77 receiver. It seems to affect only some bluing, maybe based on age or time in the bluing tank, can't be sure. But needless to say, I'm not a happy camper. If I'm right, this could be a big issue. It is with me at least. I thought about confronting the company, but without evidence I,m sure they would deny liability. Any help would be appreciated. I believe Gun Tests may have done something on this a few years ago.
