Sorry to see that. The seams in the metal...I have no idea how to get at them.

I just bought a cheap endoscope on Amazon ($20) for an unrelated project. It attaches to your phone and offers pretty decent image quality. I might use it to inspect a few hard to reach areas like the underside of the doorsills and these seams. Maybe I can figure out how to better treat them.

Just letting you know i have the same issue on 2011 G 350 in the same places.
It must be an inherent problem but shouldn't be as I thought i was buying a quality brand.

I also had the same with a 1998 C43 AMG and the said it was stone chips but i kept hassling MB and they final came to the table and resprayed and fixed it.

I'm a EX panelbeater and knew it was not stone chips but what we call a worm. It's in the metal from the start.

Not must help for you I'm sorry but your not allow.
Cheers
Mike.

If you saturate the area behind the weather stripping with penetrating grease you can mostly stop the rust from progressing.

@Texas E63 just found something resembling corrosion on my G along the seam…though it looks more like…delamination…than corrosion.

ill try and see if I can view it from behind with my endoscope…not sure if its a surface issue or not. I think at this point I’m just going to apply a small dab of penetrating oil, followed by a dab of red n’ tacky, after every wash. It’s barely noticeable but I don’t feel like having it sanded/painted. I might even create some kind of “stencil” with which to cover the surrounding area so I can work without getting oil elsewhere.

I would mask it all off so only the defect is visible, Take a pinpoint dremel tool, similar to the size a dentist might use for a cavity, grind out the rust/defect, paint with POR 15 to arrest the rust, and the touch up with your color topcoat.

I did something very similar on my 20yr old Porsche Cayenne recently. Turned out fine. I should have done a year ago when I first spotted it. Rust is not like wine or cheese, it doesn't get better with age.

I would mask the off each side of the seam, sand/grind out the loose/bubbled paint. Then paint seam with POR rust converter, top coat it with appropriate color touch up and it should be almost invisible.

Duplicator sells that in a spray can - just make sure you tape off at least five feet in every direction and use fans to draw/push air away from the car because even light coats up close will spread through the air and land on the vehicle.

I have also had great color match with TouchUp direct.

The small touch bottles (base plus clear) are likely perfect for seams.

Hello,
I'm new to the forum and this is my first post...
I've always wanted a G-Wagon, but reading this thread has me looking closer at Range Rovers. Is there a range of years that the G series are less affected by the rust issues?
Have they fixed the issue, and if so, what year did they do it?
Thanks in advance for your response.
Dan

Range Rovers are absolute garbage from a reliability standpoint.
While rust is obviously an issue with older G Wagons (pre-2019) it’s not that common or there would be a lot more complaints.

From your post, could I assume that 2019+ G's don't have rust issues?
I owned a 2006 L322. It was some work, but all in the drive was good and having bought it used and depreciated, I can't complain too much.

I have a 2019 G Wagon. It's been outdoors 24x7 for 4.5 years, through Canadian winters. No rust at all. They made significant changes to the vehicle in this regard. For example, there is a sacrificial zinc anode on the doors!

The price point is a little steeper, but I know it'd just irk me every time I saw rust.
Maybe I need to adjust my budget a bit.
