2019 Jimny Rust Prevention

That's great thanks Dagzook, I'll get it ordered.

I always thought that the rust is mainly due to aggressive salt on roads. Well, Look at my Jimny, manufactured in March 2020, driven in Australia for few weeks with less than 400km on odometer. No serious offroad (about 2km on unsealed road and grass area on farm), No offroad on beaches, No salt on roads...
On protected surfaces, everything is fine so far. However, it seems that there are several surfaces which are not protected at all (e.g. every radius arm has protected only one side, while the other side is unprotected and already quite rusty)

Is this normal?
My other cars (Holden Barina + Holden Commodore) are over 10 years old and have probably less rust than this!

Hi Vercernik,

Those areas you've photographed are bare metal areas. The JIM left the factory like that, so yes light surface corrosion at exposure moisture within the first 2k miles would result in light surface corrosion.

Nothing that a cheap tin of Wax oil won't resolve.

This is a really good explanation behind the science of rust:

opentextbc.ca/chemistry/chapter/17-6-corrosion

In layman's terms, Rust will form on ferrous metals when there is a presence of oxygen, H20 (water) and iron (within the steel). The speed of the chemical reaction when only Oxygen, H20 and Iron are involved is quite slow.

BUT with the introduction of electrolytes i.e (our good friend ROAD SALT), the chemical reaction is supercharged. Hence why us Brits in the UK suffer terribly over the winter months, our roads are heavily gritted.

Found the dreaded orange stuff on a chassis drain hole.
One can of S-50 is enough to do both sides.
The 2 foot lance is a must. Not happy its only 6 moths old.

Thanks Grima! damn I've bought two tins. I'll have some left over for a second application then.

I got two of the 360 degree nozzles from opie oils. 600mm should be more than long enough to get from one drain hole to the next.

I'm sure by doing this you've kept Mr rust at bay.

As you can see its a messy job. Its like black water then sets to a wax. There are drain holes all along the chassis so there is no problem getting access. The lance 4 way nozzle is a brilliant idea. Just insert spray & pull out slowly. Only took 15 mins to do. Well worth £20.
