How many of you owners of stainless steel guns use just gasoline to CLEAN your guns? Mang Dolpho and the guys at Northstar just use gasoline for cleaning. Works pretty well. As for lubrication, well, premium-grade SYNTHETIC motor oil has been suggested on many forums (Mobil-1 or Shell Helix.) Even if world petroleum prices are increasing a lot at the moment , still the cost of using gasoline and motor oil - which come in containers as big as you want and therefore involve volume discounts - must be an awful lot cheaper than buying smallish bottles of CLP, FP-10 and such. So, my feeling is that for owners of stainless steel guns (a "rust inhibitor" not very important), gasoline and synthetic motor oil might be quite sufficient.
