I was in a crowded elevator recently and got pushed back against a well-dressed guy in a suit. As we collided, the smell of Hoppe's Nitro Powder solvent coming from him became evident.
Before thinking, I asked, "What's your carry piece?" He did not reply, but quickly got off the elevator at the next stop.
We do have legal CCW in Georgia, but it might be good to also cover up distinctive smells of oils and solvents, or do like the Japanese and add a little clove oil.
I am gonna mix some with the WD40 on my shoulder.....
