I've seen a few post scattered in other threads, and I was intrigued by some of the other "exotic" oils but I'd like to have a simple "run to any store, buy this, and apply like this". Keep in mind I've been using Hoppe's Oil and nitro solvent for 20+ years. 500 Rounds and 3 cleanings, I haven't had any issues with my XDs yet. I'll quote out of another thread so I don't take that thread off topic. I see the wear marks starting to develop on the barrel, so I can guess where about the grease should go there...just not sure "how much".
