fulloflead’s Great Rust Experiment II

Very well done, as a former "benchtop" lab type, I really appreciate the work and the methodolgy. I also see marine tuffcloth in my future!

Great info and pictures.

Now if you used Budweiser instead of saltwater how would the test come out? Use regular Coca Cola?

Um...
Do you think the government would give me a grant to continue my research? If I keep going with this, I'm going to need to quit my job, and a labratory... and a new car... one of those white coats... a monkey...

Maybe I missed it but how did the "Mil-tec" or "Militech" do in the test?

Well, during that first 12-hours stretch, it didn't protect very well, wiped or left alone. Consequently, it wasn't one of the ones I chose for the second phase of the experiment.

I suppose, one could do a shorter experiment, like my Phase II, including more products to see how the lesser products rank against each other. I was being a little selfish, though, and was just looking for the BEST performers.

This experiment also ONLY considered the protective properties of various products, not their lubrication value. Perhaps, someday, me or somebody could figure to rank the over-all performance of various products, giving them points for both corrosion protection and slipperyness. Perhaps, then Militec would rise a little higher. I doubt it, though. I've given Militec a fair try as a lube and am not impressed.

I have a feeling that, if we were to do an experiment like this, that Breakfree CLP would do rather well. I haven't tried TuffGlide much as a lubricant and don't even know if you can get (I don't think so) Marine Tuff Glide in a bottle, but that would definately be a tough race if you factored in both protection and lubrication.

Very, VERY nice work!! :thumbup:

Not surpriised Miltec didn't do well; it's a high-temp lube, not marketed as a protectant. Not nearly the same thing.

Breakfree did a lot better than I expected. Might hafta get me some again...

Too bad you couldn't've tested Renaissance Wax, too, just for completeness!

No product survived HEAVY wiping (20 strokes) and immersion for 12 hours.

I checked this a few years back on a similar steel, barteaux machetes, even a few minutes work on light grass would remove even heavy foam corrosion sprays and the blade would basically rust as if it had never been coated. Considering that the main reason you protect for knives is for the edge, I gave up on using anything except when putting blades away for extended periods of time.

Breakfree CLP performed head-and-shoulders over all ...

Corrosion is highly random in nature and effected by many conditions, you may want to repeat the work a few times including such things as rotating the tubs and order of application (you never know) to see if the results stabilize. In addition to surface coating, from a knife perspective you are also looking at depth of penetration.

I am in the middle of a corrosion check on a bunch of blades steels now, with the same solution, same tubs, same time, and while the average or total corrosion from all the runs is pretty distinct, the individual runs can vary significantly.

For example while a SAK in general resists corrosion better than a Sebenza, after soaking them for four times, once the SAK rusted worse than the Sebenza did on its best run. Thus a one shot comparison could give very different results than a repeated trial. This is true in general.

Informative, you should put this up on a webpage.

Fulloflead, this is a great service to the forum, thanks for putting your time and effort into it. I'm happy to find that I have 2 of the better performers right here at home - I figured it was my obsessive cleaning and maintenance that kept my blades rust free but I guess I'll have to give some of the credit to Breakfree and Tuf-Cloth. :)
 
Yea man , kudos on a job well done ! :thumbup:

A thought though on Breakfree (of which I use almost daily) , CLP is recommended to 'cure' before proper protection results.
Example - I have a high carbon steel , forged , handmade knife that I store in it's leather sheath , usually this is a severe no-no but after 'curing' it with CLP I have not seen a single speck of rust or discoloration of any sort and this has been in it's sheath for goin on two years.
Anyways just thought I'd toss that in there.

Also I have a big BIG complaint.................

Why didnt we get to see more of your assistant helping you in those pics ??
:D

hehe , great job bro.

Breakfree has been my choice ever since I discovered I was allergic to RemOil. Are you talking about curing the sheath or the knife?

Yeah, my assistant wasn't much help. I have a much bigger version of Beaker now, so I'll try him out.

Well the sheath which is handmade is also well oiled with mink , but yea the blade I let cure , just for GP curing , I clean , dry , warm blade , apply CLP and let sit overnight , wipe off the bulk of it and I'm done.

Yeah, too high-tech for my habits. I usually dribble, finger smear and stuff in a stick it in one of those silicone socks.

I can't get into those high-maintenance methods, which is probably one of the reasons why I never was impressed with Militec. I tried the heating thing a few times, but it didn't make THAT much of a difference and was a pain in the butt anyway.

I like products I can use without having to put much thought and effort into it. I think the Marine Tuff Cloth will be my go-to item now; I'll just wipe it and forget it, though I don't care for the foil resealable bag. Maybe I'll stuff a few into a tupperware container and then I'll be happy.
 
That is an awesome piece of science. Thank you for the effort and expense all that rigor cost you. I will surely act on your conclusions.

It's not that it's dying, it's just that you covered the topic so well, there's not much else left to say! ;)

Yo Mod dudes! Any chance of making this a sticky?
 
Great work and fantastic read! I agree with Cliff that corrosion is an odd thing ... easy enough for me to sit back on the couch and suggest you try this again someday, with slightly different conditions, but if you're ever so motivated, the results would be really interesting.
 
Hey, I'm just curious if anyone here has ever done any testing with a product called Eezox?
 
Time to go buy some marine tuff cloth!

I need to dig through my woodworking magazines, last year one of them did a test like this on saw blades - I remember the results surprised me, and that they tested a lot of funky products I'd never heard of. :D

I'll try to dig it up.

Great work, full of lead.Cliff's right, post this on a permanent page somewhere.
 
I have often heard the adage "Comparisons are odious". But "Fulloflead's Great Rust Experiment, parts I & II" ended any doubts. I now know that comparisons are beautiful.

Great work and thanks.
 
Thanks again, everybody!
I'm still using Marine Tuff Cloth for myself, but I find it leaves a nice "frosting" on blades so you have to wipe it down later which leaves a nice protection behind.

Very nice experiment! Well done.
Have you tried Bullfrog products?
Click to expand...

Not yet. Don't know where to get them, actually. Maybe I'll get bored this winter and do a Part III under some different conditons with a different method that I haven't drempt up yet.

I've actually always wanted to do a slipperyness test with a ramp and a gun-trigger-weight guage or something.
