With this heat and the way I carry sweat tends to get on my pistol. And today I noticed a tiny bit of rust starting on my takedown pin. It came right off. it couldn't have been there long seeing as I cleaned my gun 2 days ago and didn't notice it.
My question is, has anyone ever coated certain parts of their weapons to help prevent any spot rusting. Or how can I prevent this.
Thank you for any help!
