Rustproofing.

Back in Feb. 2020 I emailed customer services at Suzuki with the question " what rust proofing measures are taken to protect the Jimny".I asked the question because the catalogue stated that the Jimny had a 12 year anti perforation warranty.

The response was:-

"Steel sheets are given corrosion resistance on the interior / and or exterior. These corrosion resistance steel sheet materials are called one of two -side galvanized steel sheets.
1.Steel sheets are treated with cathodic electro primer which is excellent in corrosion resistance.
2.Rust proof coatings are applied to door and side sill insides where moisture is liable to stay.
3.vinyl coating is applied to body underside and wheel housing inside.
4.Sealer is applied to door hem, engine compartment steel sheet to steel sheet joint, and the like portions to prevent water penetration and resulting in rust occurrence.
The 12 years is for penetration inside to outside and requires a dealer check and stamp every year between 11th-12th month

I can concur that suzuki have done a decent job with wax/resin/gunk protection in doors and bentween steel sheets. Its a dark sticky wax and was nice to see.

I have now used lanolin on my chassis and in the chassis rails. It is amazing stuff and eco friendly.

Cant recomend the stuff highly.enough.

That be as it may, an unprotected Jimny will be red raw with surface corruption within 18 months and there are many reported instances of mot failure for corrosion as early as 10 years.

The gen.4 has only been out for approx. 2 years, so I assume that the measures now taken by Suzuki are to rectify the problems they had with earlier models.

Ok except for reports of new cars fresh off the ship already having surface corruption on supposedly sealed seams. As I did with my Dreadnaught I would apply a coating straight off the forecourt if I were in the market for a gen4.

You would think so, but pictures I have seen on here of some G4's have rust stains running from within the chassis, along with the normal weld seam surface rust and component rust starting. Looks very similar to a 1 year old G3 and Suzuki had a few attempts before the G3 to improve things. I personally would not believe the sale hype at this time, maybe in 10 years if they are still weld repair free.
