I think everyone has seen that test, but it does nothing for how it neutralizes black powder residue. Also, some people claim they have rust in their bores after using Ballistol, but I think they are seeing something else. I think the Ballistol has continued to loosen up crud, and when they swab their barrel and see a brown patch and think it is rust. When actually it is crud from not getting it clean enough. I will continue to use Ballistol as it works great for me. I always get a kick out the lube and cleaning discussions. They get brought up every couple weeks and get a lot of attention. Always fun. I too love the smell of Ballistol and Hoppes 9, if they didn't smell, how would you know they are working?
