Best rust inhibitor: How to prevent corrosion on your motorcycle with XCP, ACF-50, SDoc, WD-40, GT85

After a total of 12 months of testing, these are the best rust inhibitors for your motorcycle. Properly clean your bike and prep it for winter and it’ll survive the salt that can lead to corrosion and rust damage. Products like ACF-50, XCP Rust Blocker, Scottoiler FS 365 and TechCote ACS TC200 are popular among bikers when it comes to keeping rust at bay, but how good are they really? And once you’ve chosen one, what’s the best way to apply them?

You absolutely nailed that video. Just bought a bike that had ACF50 applied regularly and am pleasantly surprised at how nice it is... However, I had no idea there were products that absolutely wiped the floor with it! Thanks for making such an irrefutable and thorough test.

Such a lot of effort you put in , thank you. Previously used ACF 50 and had applied by all year biker, then one year he said I could have XCP rust blocker but was stickier so I stuck with ACF. The last 2 winters I’ve done it myself with XCP clear coat. Great review 👍🏻

It was having my bike done by AYB that I picked up on the compressor method of application; they certainly do a good job for a very fair price. Cheers, John

Another mammoth effort! Really interesting that the aerosol cans came out better than the paint-sprayers as I’ve seen a few forum advocate that paint-sprayers are the only way to go. Great testing and really informative!

A paint gun can help drive the protectant into the nooks and crannies as it mists in there, but it's not got the same level of protection. Cheers, John

A bit late but I wanted to say a massive thank you. I had been using 2 of the brands which didn't even rank. And as for "why not on brake discs" a friend of ours 20 years ago sprayed a moisture repellent all over everything (including his discs) and when he had to touch his brakes, he did a Tom cruise and "flew right by" and crashed, he was OK but not the bike. Anyway as I said a big thanks for the video, subbed 👍

[@HalfdeadRider]

I think it's best (whatever product you choose) to spray on a rag/cloth and wipe on rather than spray on, and wipe off excess, and more so just to spray on and leave of course. My bike is outside day and night all year, what I like to do is reapply on exposed metal surfaces after every wash to be sure it's as well protected as possible, a standard spray can of ACF-50 lasts much longer this way in my experience.

[@newmillennial4248]

How do you protect the brake disc carriers? Mine are starting to rust.

[@HalfdeadRider]

@@newmillennial4248 If you just want to protect with a product such as ACF-50, take the carrier off the bike, clean and dry it and wipe all over with a rag sprayed with the product of choice, none will get on your disc or pads. If the rust is more than new surface rust you'll need to sand it or get it blasted off, ACF-50 is good at removing new surface rust. Sometimes these parts are protected by paint, you could also repaint, or paint it anyway instead if you like, although you can still add ACF-50 occasionally for extra protection if you go that route.

Hi John..many thanks for the effort going into making this video ..excellent..for your kind info there is an ASTM D130 method for copper corrosion .you may adopt something similar in future if suitable ..Good luck

[@bennettsbikesocial]

Cheers... that could be useful for wiring, though the copper core's rarely exposed. Still, would be a good test, thanks! John

[@soulrebelno1]

Think I'll go with TechCote ACS TC200 spray for the bits I can see, and XCP Rust Blocker applied with a compressor for the bits I can't see! Great video, keep up the good work. 👍

Thanks very much! Sounds like a good combo. Cheers, John

Thx for your time...great vid and info. California blocks from the beach can be hard on your bike. Even with a good cover.😎✌

After the first video I started going with XCP Rust Blocker aerosol and never looked back. That stuff sticks like glue and provides 10/10 rust protection, just know it will burn away and stain your exhaust pipes.

[@FMStrazzeri]

If I may suggest something, its a very good thing to also talk about how some of these products "treat" rust after its already there. I had this on my GS's front axle bolt , and wheel weights. Scrubbed with a brass brush and applied ACF50 its went black and shiny, looks brand new and is protected. Applied it directly to my center stand that was also having rust issues and again the ACF50 blackened it out and seems to have neutralized the rust.. not sure if its permanent or if it will hold up after a thorough wash but it did seem to bring up those pieces back to a normal look. I'm not sure the other products advertise rust treatment as something they do but would be something to test and perhaps educate us as not everyone has a brand new shiny bike. Awesome content as always!

[@bennettsbikesocial]

Good call, cheers, John

[@judgejury605]

One variable you have never addressed in all your vids which is an inherent factor in engines is how these products perform under heat!

Outstanding job! Same as the previous test. Although I'm a bit surprised that, as an independent tester, you agreed to exclude some product and did the comment on Muc-Off product. You can show whatever you seem suitable for a test. That's what YT DIY tests are all about. I am actually looking for some test/comparison of wax-based corrosion protectants for engine bay of my jet ski where stickiness is not a problem. Perhaps you could recommend any. Thanks!

Brilliant . Very methodical. My plan on corrosion protection, and also for my protection , is to be a fair weather motorcyclist, and roll the bike back into my insulated and extremely water tight shed where I run a desiccant type dehumidifier . Yeah, let's not consider the electricity cost for running a desiccant type (not compressor type, they don't work in cold places) dehumidier ! I'm probably also going to use some XCP spray after watching this.

[@skianddance]

Take a bow John you've saved many viewers so much time and money! For myself just prior to watching I was about to buy Jenolite rust shield and wonder whether it might be included in your tests? and also might you use your used plates to compare rust removal treatments for use prior to applying a blocker.

[@bennettsbikesocial]

Thanks! I'll add that to the list for the next instalment. I think for rust removal I'd have to ensure all the plates were consistently corroded... one to think about for a future project. Cheers, John

[@ThomasMoore.1]

Excellent video

[@joshnolan8826]

What would you suggest for preventing rust/oxidisation on things such as brake disc carriers etc? Ceramic coat perhaps?

[@Samsonite1991]

I usually use Motul products and WD-40 to keep my bike looking nice. Instead of drying it with a machine, just take your bike for a short ride and the wind + engine heat will dry up the bike. Then let it cool down and use protective products on the desired parts.

[@antonio7334]

how does it hold up to heated parts? Such as the exhaust and engine, I've had issues with rust on exhausts and got some XCP after tons of research but worried how heat affects it. ACF I believe (maybe was XCP) says stains might be visible after heat exposure
