Thanks for sharing that very useful information. That ongoing test obviously involves a lot of effort and no small expense.

I am in the process of designing an experiment, process and device to do further lubricity evaluations on these products. The first evaluation was for the coefficient of “static” friction but I fear it was lacking (even though it was a reasonable side by side evaluation) so Im working on evaluating “dynamic” friction forces. The long holiday weekend should provide me with time to get this going.

Static coefficient of friction was pretty straight forward with the weighted sled and the addition of water to eventually break free the friction forces between the two metal plates but I am devising a constant motion evaluation so I can capture the friction forces between two metal plates that are continually moving to gauge lubricity of the products as well as wear over a greater duration than the static friction evaluation I have already conducted.

Results of gun care product evaluation

Amazing. I've gotten a whole new perspective on eezox. It's still great for cleaning, but all my guns are going to get the one shot.
I'll keep lookout for the wd40 also. What I've seen so far is really expensive, but appears to be worth it compared to rust in guns.

Yes for all the praise of Eezox I read on all the forums (some posted Eezox, nuff said or don't bother, get Eezox and save your time doing an evaluation) Eezox has proven to be a big disappointment on a host of levels. I cannot recommend not use it on any of my gear based on a long list of reasons.

Ive completed the device I assembled and plan to use to measure dynamic friction forces. There are some refinements I need to make but I think the concept is pretty straight forward.











Here is a video of the dynamic coefficient of friction device in action. Its clear I need to work on the consistency of the smoothness of the big saw blade. You can hear and see the variations in smoothness.

In the coming days I will evaluate the friction reducing properties of the products I have previously evaluated for lubricity and corrosion resistance.

Your resourcefulness and creativity are phenomenal, sir. Besides that you obviously have too much time on your hands.

It would be incredibly time consuming (or expensive) but I'd love to see a kinetic friction test after the products have dried for a couple of weeks.

So overall which gun products would you stay away from, and which ones do you think are good products?

Sorry, I haven't had the time to read the entire testing process!

First off it was not a test and 2nd, I am in no position to make up your mind for you. You really ought to invest the time to read it over and arrive at a conclusion that makes sense for your applications. I would not be so bold as to tell you what to use.

I have to tell ya, looking at your new testing device and I keep thinking we are lucky there are folks around like you with minds that work like yours does. Your efforts are appreciated!

Rather than posting the day of the failure on the thumbprint portion of the indoor plates I have waited to lump the recent failures into a single post. Here they are. Again this is only in the thumb print area of the plate.

As for the outdoor boards. Board #2 has now had every product show corrosion at 29 days. Board #1 is at 30 days with the same remaining products still fighting off corrosion.

Here is an update on the corrosion boards after 43 and 42 days outside.



The last three samples on board #1 are about to give up.



Board #2 samples are all finished. Every sample is showing corrosion.



The indoor samples (after 41 days) are showing more failures. (Only in the thumb print area)

Rust prevent, WD 40 regular), Militech1, Strike hold, Archoil, 3 In One iol, Kroil, Hoppe's MDL. Mil Poro 7 have now failed along with the others that had failed earlier.

As mentioned earlier I put together a device to capture the dynamic coefficient of friction for all the products I have previously evaluated (including a static friction evaluation)

Ive tabulated the results and they are similar to those of the static coefficient of friction evaluation.

Here is a video showing how the evaluation was conducted and how excess lube actually worsens or confounds our attempts to make metal slide easier against one another. The video will show that only in the absolute minimalist state do the gun lubes actually reduce the friction/drag forces.

All the products were run through the friction device and the chart below shows how each product performed in comparison to one another as well as dry steel (no lube at all)

Ingenious set up and time consuming too. Thanks for all your work. It has reenforced my newfound confidence in one shot dry lube

After 62 days the outdoor evaluation has concluded. This past June was one of the rainiest on record. I did not post the failure date of the last three products on the date of the failure so I could lump them together. Here are the final products to show corrosion.

Frog Lube after 54 days

Hornady One Shot after 58 days and

WD 40 Specialist at 62 days.







The indoor evaluation is still on-going.

This cracked me up.
In talking about home brew CLPs someone pointed out that they stink, and one should use store bought to keep the odor down:

How would you test for that?

Someone on a forum I am on posted this link and a bit about it. My first thoughts was here is another guy dreaming up some testing which has no validity whatsoever and the results will be exactly what he happens to use.

I spent some of my time in R&D as a test engineer. Testing is neither easy, simple and it has to be approached without bias...in my years on various public forums (since the late 70's when I was on ARPANET) its been a rare occasion I saw a test worth reading past the first few statements.

I am not for sure who the OP is or what he does for a living, but I can honestly say this is the best testing procedures I have seen come out of a public forum. Granted its not a control lab experiment but I would not hesitate to say his results would parallel that of a testing lab. It was not only a well developed test, excellent procedures, but the write up actually made sense and followed a well developed logical discussion of what he did.

I registered just to make this comment.

Whether you are an engineer or not you have done a fine job by any standard or measure. Thank you for your work...

Well done !

I found this thread on TapaTalk, and it is easier to follow along on that as the images show up in the post. Hard to get the jist of this, with only links posted in Vbulletin.
