Friction Coefficient Comparison, FP-10, Weapon Shield, Anti-Seize
PappaWheelie:
Having mentioned being happy with Weapon Shield, after being impressed by a Weapon Shield video that purportedly demonstrated huge (~100X; ~8X load carried by ~1/12 the area!) advantage over competitive lubes http://www.czforum.com/forum/index.php?topic=4798.msg20569#msg20569 etc. it has been an ongoing question in my mind how such a seemingly impossible advantage could be real, and thus what real-world advantage Weapon Shield might actually represent.
I recently came across something suggesting that many of the "big guys" use a different lube, FP-10, which in my relative Newbie-ness I hadn't heard of: I ordered a bottle to do said real-world comparison with Weapon Shield so that if there indeed was a better lube I could adopt it. I offer Whomever, btw, the opportunity to advise if they believe their favorite lube is better, based on empirical data or at least personal experience comparing lubes.
I rigged up a Friction Test Sled comprising a 5 lb. barbell weight with three 3/8" ball bearings superglued adjacent the bore in a more-or-less symmetrical array. Loading another three 5 lb. weights on top produced an "extreme pressure" loading situation that in the unlubed state sufficed to produce tracks in the mild steel support surface, which was 320 grit sanded to cut through most of the surface rust, and then vacuumed and wiped down with laquer thinner.

I used my cellphone camera and the Neostar cellphone holder PeachBoy son got me for Christmas (http://www.czfirearms.us/index.php?topic=93988.msg718868#msg718868) to take movies of the Rapala digital fish scale readouts, from which I took 5X "sticktion"/low speed friction readings to average.
Here are the results:
LUBE Average Load Coefficient of friction
FP-10 3.71 0.19
Weapon Shield 3.00 0.15
Anti-Seize 2.22 0.11
This bears out the benefit of using a tiny toothpick dab of Anti-Sieze on the SA tooth/sear interface for the most buttery-smooth Single Action trigger imaginable.

After being duly amazed at the way Amsoil Severe Gear lube, bought for the differential of my recently inherited and resurrected, almost 40 year old, topless :shocked: early Yamaha G1 golf cart
https://drive.google.com/open?id=1KNPnfFQrQzg92hHviWAvTdX8ZgUQU4YT
really "slicked up" previously stuck trailer gate sockets, I thought it would be interesting to see how it performed on my makeshift 3-ball friction test rig.
I refreshed the plate, after careful lacquer thinner cleaning, using 600 grit and then 2000 grit wet-or-dry, and again used the cellphone movie method to capture peak load before sliding for both Weapon Shield and the Amsoil product,
https://drive.google.com/open?id=1RcJNM2vwXpX_wyNStv2P_JcTppG4XwQd which cost just under $18.00 for a quart at Auto Value.
The results reveal a new stiction champion, and by-far value champion: one would have to lube a whole lot of firearms to use up a whole quart!
Here are the results:
LUBE Average Load, lbs. Coefficient of friction
Weapon Shield 3.00 0.15
Amsoil Severe Gear 2.75 0.14
July 29, 2018 UPDATE:
I was so excited to publish the above last night that I did so having in reality only gotten one load video, with one single breakaway load for the Amsoil Severe Gear. I'd gotten two readings for the Weapon Shield, which (amazingly) again averaged to 3.00 but this morning woke early realizing that for fairness, consistency, and integrity I needed to get an average of multiple start-of-motion loads for the Amsoil. I took two series of seven readings, as it turned out, producing averages of 2.79 and 2.36, with corresponding coefficients of friction 0.14 and 0.12. The average of all 14 readings was 2.58 lbs., for overall coefficient of friction 0.13! So the "new stiction champion" label sticks, so to speak. Near Anti-Sieze performance without the "can't get the stuff off your fingers, etc." mess. The "90 gear oil"-class viscosity level of the Amsoil Severe Gear also represents an improvement for pistol assembly (slide rails, at least), for its greater "stay put until assembled" character (more like grease but still fully fluid). Congrats to Amsoil Product Development for pushing the bar. I see that Lucas sells a full synthetic "gun lube" in the auto parts stores but doubt that it will be competitive with Amsoil's best in terms of Extreme Pressure capacity: maybe I'll get some and prove the point.
316 reads as of this update; I've left a few breadcrumb trails on czfirearms.us linking back to this study as it seems (to me, anyway) pretty significant.

Here's the result of the obligitory testing of Amsoil Firearm Lubricant

LUBE Average Load, lbs. Coefficient of friction
Amsoil Firearm Lubricant 4.72 0.24
Nowhere near Weapon Shield, let alone Amsoil Severe Gear!
I hereby confirm Amsoil Severe Gear 75W-140 Reigning Champion Extreme Pressure Firearm Lubricant. I'd like to opine that the over-the-top PV range of Mr. Fennel's YouTube as cited above bears no relationship to the real world PVs of firearm function, so even if "real" (hard to believe as a two orders of magnitude better result seems to be), doesn't mean diddly to real world firearm "Extreme Pressures."
I thank Mr. Fennel for the improvement he obtained with Weapon Shield over FP-10, and also for producing an eye-catching promo video, but soberly observe that he's now got his work cut out for him, having been significantly upstaged by Amsoil's product development team who weren't even trying with respect to firearm lubes. Thumbs down, however, on Amsoil's product development team for the 3rd-rate EP performance of Amsoil Firearm Lubricant, which (believe it or not) has to be shaken before application!

That you for taking the time, excellent read. I would like to see more products just to see how they all compare. Cuda lube, regular motor oil, Mobil 1 is a popular choice by a few "big names" along with wd 40 etc.
Again, thank you.
