Long Term Rust Proofing Test

[andy666]

Well here is the result after 1 week. I rinsed them today to remove the salt and I'll leave them for another few weeks. But I think that the results are plain to see.

The lanox and cavity wax are the clear winners, with both showing only very minor discolouration.
The inox and canvas waterproofing were the next best performers, showing light surface rust.
The control (no coating), polish/water mix and wash & wax/water mix were extremely rusted which was expected.
The biggest surprise was the fish oil, which did sweet FA and rusted as badly as the I coated control plate. Fish oil may work well in the joints of a chassis, where it can get caught and wear or wash off, but on flat surfaces it is completely useless.

Nice work Andy!!

Looks like the kiwi aftershave is a surefire winner!

Cheers for sharing.

[andy666]

Yep, I already have cavity wax sprayed inside the chassis rails and I think that I'll use the lanox to coat the outside. I'll keep the test going for a while to see how long the lanox last for.

[furious]

cheers for this, some surprising results

[BIGFOOTJR]

Next clean I'll be doing the cavity wax/lanox combo.

Much appreciated

I thought fish oil was supposed be pretty good but obviously not Good test wonder how bad they will be at the end. Wish i could get some pit water up to you to speed the process up This stuff eats any metal surfaces and gets under paint and gal like anything

Great work mate ,do you know if you can buy lanox in a 4 ltr and use spray gun ? Looks like its the way to go wont use fish oil again

[BIGFOOTJR]

Yes you can, BCF.

Axehand cheers mate looks like the way to go do u spray your whole underbody already any areas of concern mate ?

Great to see someone willing to put in the time and effort for all to see the results. My old mechanic, a local 4x4 specialist used to tell me to simply recoat scratches with black spray paint and give it all a coverage of CRC. Your test would indicate that the Penetrol and Lanox give excellent results. How do these compare to the Inox or Fish oil for thickness and stickyness? And do they dry or remain tacky?

[andy666]

The Penetrol dries completely and can be painted over. It's actually what it's designed for. When sprayed on, it's as thin as water and gets in between layers of metal, then it dries to a hard gloss finish. I actually did all the joints in my chassis with Penetrol before I resprayed it.

The fish oil (where there was any left) was still tacky.

The inox has a very slight greasiness, the lanox a bit more so and feels like a thicker coating.

I thinned down some tectyl with kero and coated in side of chassis on jet ski, worked like a charm

[BIGFOOTJR]

Axehand cheers mate looks like the way to go do u spray your whole underbody already any areas of concern mate ?

The entire under body, every nook and cranny, inside the chassis rails, inside the doors

Where does one buy this Lanox or inox? I recently started spraying crc on , is that any good ?

For a 5L or 20L drum an industrial supply place would probably be your best bet, or somewhere like autobarn may be able to order it in.
I can't say about crc, I've never used it. The only thing would be to check that crc doesn't contain any kerosene or diesel because it will eat rubber.
Between inox and lanox I would choose lanox. It has performed better and is a thicker coating so should last longer.

[Alby]

Inox is similar to CRC but I think inbox is better, it does not wash off as quickly and is popular for outboard motor use
As andy666 said the lanox stays on better, it is made from the greasy/ oil in sheeps wool ( the Kiwis use it as a sensual massage oil )
I have used it on the bottom of my tinny to stop algae growth when left in the water too long and it does not wash off

Mate, CRC is very different to Inox. Having worked in the marine trade for years and outboards and jetski's previously. I used to see loads of 10 year old Ski's come in that have used inox and were like brand new & had a lot less trouble getting bolts out. CRC overtime destroys the plastic sheathing on your wiring and will affect plastics.

Inox will actually shine your plastics really nicely and doesn't bother any rubbers. Is food safe and not damaging on your skin either.

Best part, it's an Australian product & no more expensive than others. Lanox is about $120 for 4 litres at AutoPro currently.

The stuff is mothers milk to your car!

[Qwerty]

how does one apply it? spray can or paint brush?

I recently got pretty damn wet and salty through clay pans that had a ton of rain (was no way except through pretty huge puddles) ... whole damn lux got verry wet / muddy ... and pretty high salt content in the water (i stopped and tasted a puddle... saltyness).

Gave it one hell of a clean when i got home though (every single visible chassis rail hole with fresh, then karcher under for about 2hrs up on a stand) ... but even so there's plenty of surface rust on chassis where paint has been chipped, and surace rust on my back axle (where sand / terrain hs stripped paint back over time) so id like to hit it with something that will prolong its life.

[StevenS]

This is a very handy comparison, but one thing Im concerned about is the durability of the different coatings

Ie out of the 2 best, being lanox and cavity wax, which would last the longest before recoating is required? For example cavity wax might not be the better for short term, but more economical in the long run

[andy666]

For the outside of the chassis where you might want to paint over it, give it a hit with the penetrol to seal it then paint over it.

Edit: spraying it on would be the best bet
