So, i guess i should let you gents in on a little secret...
most all of my internal components have been treated with WPC surface treatment.
this has been on the Import scene for a while, and an NHRA little know deal for some time as well.
they have a US location now in Torrance California
List of parts that have been treated in my engine:
rocker shafts
rod bearings
main bearings
cam bearings
wrist pins
oil pump gears
oil pump drive shafts
piston skirts.
fuel pump pushrod
things that i could have done, but didnt.
cam journals
crankshaft journals
lifter bodies
pretty incredible stuff.

WOW, WPC mopar internals, I wonder if you are the first, lol..
I had a turbo built in japan and they use this process, that turboo is on a 15k rpm engine and never had an issue with it. A friend of mine who builds motorcycle engines showed me the process, it is expensive and they do it in japan a lot... Probably explains the tuner crowd having it..

What did it cost to have the WPC done, if you don't mind my asking?

Got a newly rebuilt 440 in the shop some years back with the owner complaining about no oil pressure and couldn't find the problem and brought it in after doing the normal checks and oil pump replacement etc and after sticking in on the stand and pulling the pan, I found all the bearings installed upside down. With the engine turned over, it's pretty easy to do that if you're not paying close attention. Thing is, a reputable shop built this engine. Scary stuff for sure and it was too bad that no one noticed it before firing it up because it blackened all the rods and messed up the crank. You dodge a bullet for sure.....a lot of people do not check to see how much torque it takes to spin over a fresh engine.....

Being a Long Range shooter this looks like Hexagonal Boron Nitrate coating (HBN) for large scale parts, I'm willing too bet it is..... Steel shot in used too impact plate the HBN on too the surface of the part and alter the parts surface finish with little micro dents, this lowers the bearing surfaces contact area and traps the HBN in a divot, now there a fine layer of HBN on its surface. HBN aka white graphite gives the plated part its milky like color. Shooters discovered HBN as a cleaner alternative too Moly coating, HBN doesn't have the history of attracting moisture and rusting rifle bores and is easily cleaned out with bore solvents, unlike Moly.
HBN's best quality's or attribute is that its a super slick lube under pressure and nonreactive. And not too steal your thunder or burst your bubble but you could have done the same thing at home with a large or home made tumbler a bag of washed steal shot from the gun store, HBN Nano off the net and plated your parts at home for a lot less money and still reaped the same anti-friction rewards. I don't know the grade or size of the HBN there using but you can get the ultra fine Nano(under 5micron) for under $20.00 with shipping and that would be more than enough too do 50+ engines. The Nano is so small it will pass threw and wont get trapped in oil filters.
It would also be a good idea too have some too replenish your oil after changes, if your going too retain any of its benefits. About a 1/2 tea spoon size amount and that would almost be overkill. If there is a down side too HBN its that you should not breath the dust when opening the jar, after its been plated its hammered into the part and you don't have too worry about particles floating off.

WPCs process is very Proprietary, i have never been able to actually watch the process.
what i do know is yes, the blast the parts with high pressure micro spheres of some sort of moly something product. it is shoot at a high enough presure that it dose restructure the surface of the part its applied to, but dose not change the bearing surfaces for oil clearance.
funny you should mention firearms, im planning to give them a couple of AR15 bolts for shits and giggles to see how they work after the treatment!
