What is the Best Rust Preventative? - 9 Month Update

[@ericyeoman2687]

de-oderised Fish Oil. I have used this in car door sills over the years. creeps around in hot weather into all the seams. cheers.

[@supernova1976]

Just found your channel yesterday and watched the 6 month update,. thanks for the long term test 👍

[@StuartdeHaro]

Well welcome aboard! Thanks for watching!

We use and recommend LPS-3 to our customers when installing our T-Slot Covers.

[@TradeWorks_Construction]

While not a direct application rust preventative and certainly not one to be used in the exposed elements I’ve found reusable gun safe desiccant canisters or even the smaller packets wrapped in breathable membranes similar to tyvek on buildings help a lot for anything that is covered. With both you can refresh their moisture trapping ability by placing them out in the sun on a hot dry day or in a toaster oven on low heat. They have made a world of difference in preventing rust from creeping on to the tools in my tool box and might be worth considering to include with equipment under long term storage with a tarp. I live in Seattle so my unconditioned garage has become my proving ground for my quest to find the ultimate preventative. Interestingly enough the single biggest improvement came when I prepped the concrete floor for 3 months and applied an industrial grade epoxy floor coat (3 months prep because the 900sqft garage had been used as a mechanics garage for the last 50 years and oil intrusion forced me to rent a walk behind surface grinder after multiple attempts with hot pressure washing & industrial degreasers failed) Rust mitigation will always be an integral topic for just about anyone who cares about their stuff. Great video and appreciate the honest and careful assessments you provided.

Defeating rust in the Pacific Northwest is an ongoing nightmare😢

[@egx161]

Dupont Molykote metal protector plus. It’s wax based fluid in a petroleum distillate solvent. Not sure anything works long term outdoors. Some products seem to trap moisture and create even more rust. Road salt and harsh winters are difficult to defend against. Washing , waxing and keeping your car indoors is the only way in those conditions. Trapped moisture is the enemy. There isn’t much that can be done for outdoor metal. Hot dipped galvanized or paint are good options. Hot dipping is very expensive but works best.

[@bkoholliston]

LPS 3 has always been my favorite.

[@StuartdeHaro]

It's certainly mine so far.

[@WallsOfAbaddon]

Would love to see 'dinitrol' be tested. Loving this series and just found your channel!

[@-Kerstin]

When you start season 2 I hope you apply the rust inhibitor to all sides and edges thoroughly. Also that all pieces of steel are identical bare steel. I guess one more suggestion is that you think long and hard about the list of products you'll be testing and that they are products you think will perform well. Looking forward to it!

[@Skip11AM]

Great series of vides! However, your "confession" about the last two metal pieces introduced some havoc to my own ranking... In the second round I would like to see XCP Rust Blocker, XCP Rust Blocker Clear Coat, Jenolite Rust Shield, Jenolite Waxoil Spray and DINITROL 81. These are the ones, along with CRC SP-400, which I tested and would like to see how they compare with the rest.

[@muzzarobbo]

i was going to make a homebrew combining mineral turpentine, mineral oil and anhydrous lanolin. I have been pleased with the Inox MX3 spray and thought it would be good to be able to vary the mixtures for different applications. The same company makes a heavier duty spray called Lanox MX4 which has more lanolin in it and hence provides a thicker coating

[@cherigriffith724]

Great videos and information that you take the time to do them- that is amazing! I don't know if it's been brought up but something you could try with all them rusty plates is Evap-o-rust which I know works, but they also market a water based rust inhibitor to spray on right after rinsing to prevent rust for up to a year til you're ready to paint. It washes off with water so it would only be good for an inside test

[@StuartdeHaro]

That's a nice idea. I wouldn’t mind seeing what's under the rust actually.

[@cherigriffith724]

@@StuartdeHaro I came across a recipe for homemade chelating agent - something with grain in the AG industry? I couldn't find it and it was a little beyond me evapo-rust can be expensive, maybe you're up to the task...

[@OraDeCulcare]

i also bought Renaissance Wax wich i applied to my carbon knives and brass stuff and it works great, it is museum grade acording to its label

[@cherigriffith724]

I just suggested this in an older video I hope it makes the cut. Appreciate your feedback on it

[@bigjsknives]

Great thorough info!! In the knife game we like the mix of beeswax, olive oil, coconut oil!!

[@StuartdeHaro]

I already have a suggestion of beeswax and boiled linseed oil on the list. I'll have to swing by my favorite local orchard and get a block of beeswax, and I guess while I'm there I'll pick up some apple cinnamon doughnuts. It would be rude not to.

[@jackfrog]

Great series! A rust inhibitor I would recommend is camellia oil

[@StuartdeHaro]

Thanks, I'll check it out.

[@revionack5550]

Getting interested in your experiment since I am working on my car and trying to find out the best way to protect screws from rusting. Could you try a bunch of other rust inhibitor? My ideas would be: - cold galvanization using a spray of zinc. My research on Internet seems to show that lot of people are getting long lasting protection with it. - one of those inhibitor combined with epoxy. In an environnement without any physical impact, it should last way longer than others. For my specific use case, it would be awesome that for each piece you could use half of the metal piece to simulate gravel impact from time to time. I would also love to spray some salted water to simulate driving in winter. Thank you for your experiment !

[@pragmatist7455]

Would like to see a shootout with ACF 50 and XCP (particularly against LPS 3)

[@vizardesign]

Awesome test! Please add any but not from WD, Dry PTFE because there is mostly none tests around

[@Alex9501950]

Hey man, I just found your channel in my feed. Watched all your rust videos and I'm definitely subscribing. I recommend that you try a rust converter like Ospho. You could use your control from this test if you wanted, since the part needs to have rust for it to work. I use ospho on my outdoor welding table. It has worked great in preserving the material without leaving weird films or flamable coatings. What I use for parts I plan to store long term is just sticky red marine grade grease. Put on a glove. Slather it on. No rust for years. Awesome vids man. Excited to see where you take this.

[@cherigriffith724]

I Ospho'd my crab cookers when I cleaned them up, which they probably would not endorsed doing. It has not completely kept the rust at a bay (so OR coast) but they have not caught on fire😅

[@Alex9501950]

​@cherigriffith724 yeah, direct exposure to salt water is probably the worst case scenario. If they rust I'd recommend wiping off any of the loose rust and hitting it with more ospho. Eventually you end up a super robust layer. My outdoor welding table and vice get treated every year and at this point you hardly see any rust even after a year outside in the pacific north west.

[@Nickrioblanco1]

Interesting test. You should create a playlist of these test.

[@StuartdeHaro]

Will do.

[@37yearsofanythingisenough39]

Might I suggest you add STA-BIL Rust Stopper. I use this on the bottom of my mill vises & etc. before bolting to the table. It seems to do a good job of preventing “vise shadow” on the table. I use coolant.

[@StuartdeHaro]

I believe that's on my list from one of the older videos. Was that you that suggested it before?

[@37yearsofanythingisenough39]

@@StuartdeHaro I might have, but do not know for sure. I believe I mentioned to you once upon a time about keeping my mill vise off center to even out the wear on the lead screw. Maybe I mentioned it at that point. (That also leaves room for an indexer or rotary table by the way)

[@StuartdeHaro]

@@37yearsofanythingisenough39 I was doing the same thing for a while, mostly because I had my dividing head set up at some point and was too lazy to move the vise back.

[@gregorykuhn2552]

A bit pricey, but you may want to try Amsoil Metal Protector. They have two. A "Regular" and "Heavy Duty" product.

[@RockStar-nc6cj]

Could you also do a sample using Turtle Wax, or Mother's, without wiping off the residue.

[@StuartdeHaro]

It's on the list!

[@bwcordes]

Great update. Ill continue to use the cheapest thing available for indoors based off of this test. Im rethinking my summer rust inhibitor plan for my cars though. I would be very interested in the outdoor test, but with some shade. Im guessing that the sun is baking off most of the coati gs. I would like to see used motor oil in the next test. It does great in hard to reach spots in my experience, but who kows about a flat surface. Finally, another teavher i know tells dad jokes all the time. He said he must because though he has no children, he and his wife are really practicing for it. Thats not what he meant, but his students went a different direction...

[@StuartdeHaro]

I like the idea about the shade. Used motor oil is on the list from one of the earlier videos. Luckily, I just changed my oil.

[@user-of-apocalypse]

Thank you for all your experiment's. Can i ask you taste in next your video's take a experiment with Rust Check? Thanks.

[@StuartdeHaro]

I'll check it out.

Very well done.Thank you.

[@jbrownson]

Thanks for this series

[@emilja.4205]

Mustie1 Bar & Chain oil just a little bit thinned out enough to use with spray gun

[@Rottingboards]

I hope you do LPS again so we can see how it stands up to fluid film. How about the smell test? I hear fluid film has a smell. Does that smell go away with time? Will my whole garage forever stink when I enter it? Subscribing!! Great test! Thanks.

[@robest334]

The only lubricant that i have here is the regular wd40. I just used regular wd40 as antirust for my steel bike. Hope it protects the inside of the steel tubes.

[@doppelmax1874]

try waxoyl hard wax they also make a product for inside doors and other enclosed places the next time

[@Jnig593]

Could you please add The Flood Company Penetrol to the experiment? I believe it would hold up outstandingly. Thank you,

[@justinchaney2000]

Hey Stuart! If you dont mind, would you add unsalted butter and olive oil to the list? As a gag test you could also try beard wax. Gotta keep those mild steel samples looking as dapper as your beard haha. Best regards

[@StuartdeHaro]

Ooo, that's gonna go rancid so fast, but I'll do it...FOR SCIENCE!!!

[@Rottingboards]

Try CRC 6026

[@johnstrange6799]

I'd like to see plain old paraffin wax as a next round inhibitor.

[@StuartdeHaro]

I'll give it a shot. I'll already be doing a 50/50 mix of linseed oil and beeswax. That will be pretty thin though and applied to a hot part.

[@supernova1976]

@@StuartdeHaro This mix sounds good

[@roelzylstra]

How do you think Rust-Oleum would fare against LPS 3?

[@StuartdeHaro]

I actually was thinking of putting a paint in the mix for the next round, probably just a clear coat so it doesn't throw things off by absorbing or reflecting more light than the other samples.

[@wktodd]

Did you coat both sides? Just wondering if the uncoated part would indicate material type.

[@StuartdeHaro]

I only sprayed the side shown in the video, but the metal doesn't have an obvious coating like galvanized steel does. I didn't think it was tin coated either since that tends to have a darker hue. I'll have to ask him what it might be.

[@wktodd]

@@StuartdeHaro I was thinking that you might compare the undersides of the plates, if the known MS plates appear similar to each other, and the odd ones different then the material is probably coated or a different alloy

[@StuartdeHaro]

@@wktodd I'll check it out

[@randypankau1991]

for another product... There is an electrician here who used PB Blaster surface shield on two F150s. says it's better than Fluid Film.
