Great test! Thanks for taking the time to do this.

Its been 288 hours (12 days) since Board #1 was placed outside and 264 hours (11 days) for Board #2 so I thought I would update. There has been some rain this week but lots of sun and wind and the trees are spreading all manner of pollen and debris in the air. The Sun’s UV rays have all but made the sharpie marker unreadable but I have a map and can still make it out enough to see.

Here are the two boards where they are residing on the patio.



And here are the close-ups of the samples.





As for Board #3 in my house. Its been 240 hours (10 days) and as expected, the indoor protection in a constant environment has them all still in fine shape.

We have been experiencing torrential rains and flash flooding. When it isn’t raining its very humid. Its certainly been a wet spring. The UV rays have now completely erased the sharpie marker labels on the boards but I know which is which from prior photos. Here is a picture of the two boards with board #1 at 15 days (360 hours) and board #2 at 14 days (336 hours). The top 3 performing products are continuing to protect the steel plates.

What a test and those three products are absolutely amazing under those conditions!

DUDE whatta test! Large corporations would've spent HUNDRED$ OF THOU$AND$ and the government would've spent MILLION$ doing a test like that and I doubt they'd have been ANYWHERE close to your results!

I'm familiar with and have used several of the tested brands over the years and I typically use Royal Purple, CLP, RemOil and BWCasey products for my firearms and fishing tackle. I'm likewise familiar with the wool/lanolin based Fluid Film lube for my farm equipment as I was given a bottle by a John Deere dealer and found it to be pretty good stuff for corrosion resistance and lube, especially on the 3pt, PTO and attachments of my 70hp tractor. But I see I'll DEFINITELY be adding a bottle of the WD-40 Specialist to my tractors tool box!

Thanks again, that's an amazing, well thought out and easy to understand, "real world" test!!!

ps
This board is doing ITSELF a dis-service if this entire thread isn't made a PERMANENT sticky and even archived elsewhere!

Its been 20 days since I started board #3 which is the indoor board with the (hotdog) fingerprint.



The first (and only) sample so far to exhibit corrosion has appeared. The rust is only in the fingerprint area. The sample plate is the one coated with Eezox.



For all the positive comments about Eezox, it has been a complete disappointment in lubricity and corrosion resistance.

We'll done and thanks for sharing.

Update on the two outdoors corrosion boards. Hornady One shot has finally failed on Board #2 Leaving Frog Lube and WD 40 Specialist but the Hornady product is still going strong on board #1.

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.

I can't wait to see what you come up with to do that!
