Corrosion-Resistance and more

MolyFusion is different in that it contains no MbSO2 so it's not black. It's a light green solution of Molybdenum Phosphate with a viscosity slightly greater than water. When applied, it chemically changes the surface of the metal -- it's almost like chemically case hardening and polishing the metal at the same time. There's no measurable change in dimensions, but the increased slickness it very apparent and the shine of previously polished steel is considerably reduced -- even gray. It certainly does some things, and those things certainly seem to be all good!

I've applied it to the slide rails and hammer engagement surface on the slide. From just that and without grease or oil, the action is remarkably smoother compared to grease lubrication.

For this pistol, the next thing is to strip it all the way down and treat the hammer, trigger bar, and slide stop. I'll also treat the hammer axis pin and any other steel parts that "need" lubrication.

I'm not going to treat any springs because I'm not sure what effect making their surfaces harder would have. ShooterSolutions says that MolyFusion changes the chemistry of the metal to as much as 0.002" below the surface. That's fine, IMO, for inflexible parts, but every molecule of a spring is involved in flexing so I'm not quite ready to mess with springs.

BTW, one of the promised characteristics of MolyFusion treatment is corrosion resistance. I understand that treated steel parts have been brine soaked for extended periods with NO corrosion! For C.C.W.'s, that will be a tremendous boon -- not stainless, but zero corrosion!

QUESTION: I've used Molybdenum Disulfide before and it sure makes your hands black!

ANSWER!

I've used Molybdenum Disulfide products before. The black MbSO2 particles are like tiny plates. You know how the cards in a new deck of playing cards are slippery? The MbSO2 acts like that. However, they are only on the surface of the metal instead of becoming part of it. It gets into the crevices and canyons of the apparently polished metal, which increases the performance of lubricants, somewhat like cast iron does. (Cast iron has tiny pockets of carbon throughout, and that's why it's an excellent bearing surface.)

I've used MbSO2 in the oil of high performance engines and obtained it in quart cans containing 50% MbSO2 -- very expensive, but it was worth it! The problem with it is that it must be constantly renewed -- it's not permanent.

MolyFusion is different in that it contains no MbSO2 so it's not black. It's a light green solution of Molybdenum Phosphate with a viscosity slightly greater than water. When applied, it chemically changes the surface of the metal -- it's almost like chemically case hardening and polishing the metal at the same time.

Previous statement:

I got the MolyFusion and applied it to the barrel, steel guide rod, firing pin, and slide of a Kel-Tec P11. To cut to the chase, I'm VERY impressed!

I had previously buffed the barrel to a high shine, especially the part visible through the slide ejection cutout. MolyFusion definitely changed the surface, which now has a shiny gray appearance. Its surface is MUCH harder than before as determined by trying to scratch or even mark it with the back of a case hardened knife blade. Anecdotally, it seems about as hard as a steel ball from a ball bearing, but it's much "slicker" to the touch.
