I've always been searching for the "perfect lube" for my folders. After I stumbled onto militec I figured I'd just about found it, lubricating any metal to metal pivot I threw at it better than anything else. Now, the only local place I could find the stuff was a high end performance mustang shop, who sold the large 8 oz bottles. Whilst trying to clean up around the place last week I noticed I still had a crapload of it and really aught to find something else to use it on. I pop over to militec's website for some mixing ratios and whatnot and here I find they now claim it protects against corrosion 3x better than CLP. So here it is, my 3 way lube/protectant shootout, super condensed version.

Ferric Chloride (5 minutes): None of them faired particularly well, although the CLP did hold out the longest. On removal both the militec and Ballistol were about equaly etched, the CLP about half etched-half bright.

Saltwater( many days): I decided to let it soak for a good while with the saltwater, because it acts so slowly compared to the other two liquids. Militec was the first to show signs of corrosion, at the 30 minute mark. After 4 hours the militec was a dark orange brown color, Ballistol was a very light orange, and the CLP was still corrosion free. Fast forward a few days, and all the water in the dish I had the plate soaking in had dried up and left large salt crystals all over. At this point the CLP was still almost completely corrosion free with some light speckling of rust around the edges of the sample area and a very light dark spot where one particularly nasty salt crystal was. The Militec is covered in a dark flat brown surface rust, and doesnt look any different really from the unprotected parts of the plate. Ballistol fares a little better, the metal is still shiny, but it's an orange color with some visible etching in a swirl pattern (that I used to appy the oil with)

Vinegar (30 minutes): Militec was the first to show corrosion, at the 5 minute mark it had started turning grey. 30 minutes later the militec surface had turned brown, the ballistol was still bright, and the clp had become a misty grey color. Washing the plate off showed the the Militec had a light grey surface etch, the CLP a very light yellow tint, and the Ballistol was still bright.

On a side note, the vinegar soak was the only one that made two of the products, breakfree and Militec, to smell really nasty when I took them out. Ballistol didn't have a smell at all, but the Breakfree had a rancid odor to it, the Militec smelled similar, sharper but less pungent.

Overall Breakfree really came out as a far superior general protectant to ballistol and Militec, which was particularly dismal. It should be noted that I ballistol might actually perform a bit better than I indicate here. The stuff is capable of mixing with water for a while after it's dispensed, but after a while whatever allows it to do so (I'm assuming the alcohol content) evaporates. In hindsight I didn't really give it enough time to "settle" as it were, I might try this again giving each protectant an hour to evaporate volatiles so it's more representative of real world use.

*I actually did these 3 tests twice, once with the militec applied to cold metal, and the 2nd series with it applied while the metal was good and hot, as per their recommendations. The results for both runs were pretty much identical*
 
Thanks for posting this Yoda.

(of course, I told ya Breakfree was best years ago) :)

Informative post, you might also want to look at wear resistance. Some of them may come off very quickly with use, some might not

I might just be missing this on the Ballistol web site, but does it come in anything other than a spray bottle, like maybe a small squeeze applicator? Yeah, I know I could pour some into a small bottle myself, but I'm just curious. Sounds like this might be just the thing to keep my prospective Active Duty safe around salt water. I would prefer Ballistol because I sometimes use my knife to cut apples, oranges, etc.
 
Well, it also comes in small aerosols, but I think the best route is to get a 16 oz bottle and fill up smaller applicators. I think Ballistol will work fine for that application, so long as it has enough time to evaporate the stuff that lets it mix with water.

Cliff, that sounds interesting, but I'm not really sure how to simulate real world conditions. I think you did some reviews in the past that showed that no oil or other protectant lasted through a days field work.
 
Ahh finally, round 1.5. Finally got around to testing FP-10(my new favorite lube) and Break Free. I'll be adding to this post and the first one later one when I finish the whole round, but for now I'll just post each result as it comes along so I don't forget. This time I'm doing thin film resistance in addition to the original set of tests above, only saltwater and vinegar this time though, I don't see much point in the ferric chloride soaks so unless someone really wants to see them I wont bother. The thin film tests are similar to the original set, but in addition to straight application I'll be wiping the surface down with a clean tissue to remove all but the thinnest film of lubricant/protectant possible. I'll mark the thin film tests as such.

Round 1: Saltwater soak.

Normal Application: Good signs here, unlike the militec the FP-10 was neck and neck with Breakfree after over 4 days, including one where all the water evaporated leaving large salt crystals on the test piece. After re-saturating it I waited 2 more days (for a total of 4) and no corrosion at all was noted on either the Break Free or FP-10. Note how the performance of Break Free seems better this round even though I took care to use the same application methods and clean steel. This is why you use a known factor as a control whenever you test some new thing, comparisons are unreliable if you don't, even if you use the same tests. Had I tested FP-10 alone I would have declared it superior to BreakFree, when that may or may not be the case.

Thin Film: To be Posted

Vinegar Soak: Later.
 
Was the metal heated after applying the Militec? It says on their website that to get the full benefit low heat should be applied to the metal. It would be intersting to see if that makes a difference.
 
frank k did a review of rust preventatives a while back:

Militec didn't do very well in frank k's tests either. I think Eezox came out on top. Militec also evaporates faster than Eezox. I've oiled Micarta with both at the same time, and after sitting for several weeks the Eezox side was still dark while the Militec side was light and dry.

I'd really like to see a comparison of these with grease lubes like MD Labs XF-7. In my experience XF-7 has much better staying power (resists wiping or washing off) and hasn't dried out in the months I've used it. XF-7 is also food-safe, which makes it even more useful for me. I also coat the bare tangs of fixed blades with removable handles to prevent liquids from seeping under the scales and causing rust.
 
I too have been raving about Breakfree , an older Gent told me about it a few years back and since then I use it on just about everything , even at work on high dollar register printers.
For best results if you use BF CLP on something , let it 'cure' overnight.
Use it on your firearms and you wont go back to smelly solvents and messy oil , this works all in one style and youll also find cleaning after firing is way easier , less time consuming.
Breakfree is
the stuff

The only thing heating the metal seems to do with militec is increase the rate at which its lubricating properties start to come into play, it also spreads better when warm so it penetrates tightly fit parts better.
 
Yep missed that part, sorry. Interesting though. Ive used both BF CLP and Militec and regard both very highly. Ive never really relied on Militec for its corrosion protection (which seems very little, according to your tests) but it has loosened actions (gun,knife) a little better than CLP in some cases.

Maybe I missed it, but I did not see any comparisons of untreated metal in your test. How did these perform compared to that? Thanks for the review.
 
I did the tests on a single piece of steel plate, with each section clearly delineated by scribe lines, between each sample though there was a small area, roughly 1/8 of an inch wide to prevent cross contamination. Militec did not provide signifigant corrosion protection in any event, though it was better than completely unprotected metal the difference was small enough that I wouldn't use it in any situation where corrosion prevention was a requirement. In the saltwater tests it didn't provide any protection as a matter of fact, it was as if I had never applied it at all. The other tests were much more short term, and I think that the most likely cause of militec performing poorly in the saltwater soak was that it lifted off the steel over time.
