Boris Thank you for your words , it impressed me too so is more than a gimmick
what i did was grind some plate 1030 steel to a bright shining new metal surface
put regular oils in stripes up and down and then did 2 either end with SBGO
2 weeks in the weather here and all except two had started to rust ..
actially the synthetic motor oils protected better than a big name gun oil !!
but SBGO did the best , no rust what ever
love the BB idea , i may just do that here
