Leather body, Kydex outer. Full coverage on the leather side beaver tail to muzzle.
Tighty-Whities and a T-shirt, holster, work shirt tucked in over all, denim pants. Moisture only forms on the part of the frame touching the leather.
I do have corrosive sweat. If it is not silver or gold, it will corrode away at any point touching my skin.
Now, I rarely sweat to the point where there are wet spots or dripping off. Even on slow, sitting around days it still happens.
I think that a re-coating of some sort is going to happen soon.
Wear on the gun I accept. That is going to happen with daily wear. Rust however annoys me.
The manufacturer of the holster is me, so I think I may try boiling the leather in Wax to seal it. If that does not do it, then I may have to try to get some horse hide.
Thanks for the input guys. I have some things to try now
