View Full Version : birchwood casey "sheath"

has anyone else noticed that these high tech rust inhibitors like Sheath cause bluing to turn a reddish cast on some bluing. I'm pretty sure about my suspicions If so, doesn't the company have some liability here?

but I haven't noticed anything like that; I would think if you could prove it was the sheath, they would be liable.

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.

I have never seen this on my Ruger #1's

You can remove all the Sheath with acetone from metal. THe metal should then be whatever color it was before.
A lot of scopes are rubber-covered. Sheath is not meant for rubber.

I remember when I worked at Cabela's about every other month we wiped every gun down with "Sheath" to protect them from all of the handling.

Leupold scopes have aluminum tubes, so they are not blued, they are anodized. Exposing anodized aluminum to hi-UV light can cause themto fade or discolor, but I doubt it's the Sheath.

I realize it's anodized aluminum. It is an older scope I had on a Sako 222 rem. that spent most of it's time in a gun safe. Sheath is a new generation of rust preventatives that have a polarization quality I don't fully understand. I'll keep monitoring the thread. Thanks for the input.

Thanks' but this appears to be a permanent chemical change in the bluing. On the Mod 19 S&W I can see a narrow area on the barrel where the rag transitioned from the frame to the barrel where the bluing is unchanged. This is right by the front of the frame, on the bbl./ frame junction. I'd sure like to get ahold of that Gun Tests article. I never subscribed. I just remember that they said that the new generation of rust inhibitors had them seeing red.... literally!
