Rear inner wheel arch liner?

Hello,

I’m new to the forum and recently purchased my first Jimny on a 2000 W plate which was an MOT failure. It had the common rust in the boot floor and that has now been fixed however there is also a lot of rust in both rear wheel arch’s, the front wheel arch’s have a plastic inner liner however the rear arch’s don’t, not on mine anyway.
Can anybody tell me if there should be plastic rear wheel arch liners? I can’t seem to find any online.

I don't believe such a thing is available I have never seen one

Thanks, I will keep looking but if not, looks like plenty of Shultz once it’s patched up.

Second vote for no such thing. Also if you are feeling brave have a look at the front body mounts under the plastic liner, they hide another rot spot.

Many liners only prevent washing. Fine dust that sticks to the surface and slowly grind away the rust preventive coating is the only thing that gets behind the liners. Liners also hold water in the sticky dust making the rust wet for longer periods.
If the owner wash the car more often on the underside, and top up the coating, it will most likely rust more slowly or not at all.

I don't wash too often sadly...
Not well enough at least..

Thanks for the heads up, I better check these body mounts too.

I can't blame the plastic liners for Suzukis woefully inadequate rust protection, but they are an excuse used by most manufacturers not to protect the area behind further. If you can remember the days before wheel arch liners , i.e back in the 70's Hillman and early fords, the top of the wings was a mud trap and soon rotted through. Liners stopped this overnight. Imagine our Jimny's with the primer only under wing protection, how long do you think that will last!
I believe the front mount rot is not due to the liner, its poor seam sealing on the multi layer metal joint below the headlamp which also doubles as a water drain route. Poor design meets poor rust prevention equals rot spot. They are guilty however of hiding this rot spot until its too late to do anything.
I for one would keep the liners, I believe they offer more protection than running the vehicle without.
However it is a wise to remove them and rust proof underneath, also treat the mounts with wax at least once before the rot starts. If you do remove them I would suggest you need to add a protective coating under the wings or the vacuum tank (switch 4x4) and wing tops / A pillar will be your new rot spots.
Of course just in my humble opinion.

Thanks everyone for the replies.

Sadly I think I am way past the point of preventing the rust however your input has given me places to look so I can treat it.
My Jimny is 20 years old and the last owner lived right by the coast so you can imagine the extent of the rust. That said I'm not giving up, I've been away, hence my delay in my reply and I'm now eager to get started again.

Right, time to crack on.
