Screws on the door suspension corrode/rust

[Lyros]

Hi,

I got my Grenadier back in June ‘23 and I noticed that all of the screws in the door suspension seem to corrode/rust.

Does anybody have the same experience on their vehicle? My car dealer hasn’t heard about a similar case yet. I have my first inspection coming up and they will have a closer look at it.

Has it gone through through car wash? Have you washed your Grenadier?

Though I haven't applied any on my IG yet, I use ACF 50 on my '91 D90 and LR3.

I only hand wash the car occasionally. It’s also wax sealed from beneath that’s why I don’t want to go through a car wash.

But even with using a car wash I expect these parts not to start rusting within a year.

It looks more like a galvanic corrosion.

It was asking because like with the L track, certain soap is leaving a film on the parts.

ACF 50 or similar on all the bolt heads and they won't rust.
l use XCP rust blocker, it's a similar product and comes in rattle cans.

l sprayed underneath my 2022 Defender and after two Winters it still looks new.

I agree with crashnburn: galvanic corrosion or just crap plating

Spray it with a rust prevention product.

lt's not just the Grenadier. This is a new Defender left untreated underneath.

While the corrosion isn't structural, it's not pretty. Compare it to mine, above.

Hi crashburn, Thanks for the heads up on ACF 50.
After seeing your post I did some research and came across this 1-year test.
Based on your recommendation and this 1-year test review, (see link to it below), I went to Amazon and
purchased it immediately. Found it for just $21.99. DaBull

My year long ACF-50 vs WD40 vs Naked rust inhibitor test

Last year I'v got some ACF-50 rust inhibitor that I used on my vintage bike. It is not cheap so I wanted to know that I purchased snake oil or some real rust protection. My DIY test is not scientific at all but it is controlled enough to be useful. Stage 1: Soaking. Test mediums was sprayed...

Re apply the product once in a while. Take a piece of cardboard and make a hole in it, then you can spray the bolts (through the hole) without getting the product all over your paintwork and it only takes a few minutes to do every bolt on the vehicle.

Wait for a nice day and then do the underside of the vehicle as well. Re apply annually.

Great suggestion on the cardboard. Never thought of that. I just always do a quick wipe after spraying. Now those Amazon boxes will come handy

I genuinely feel sorry for those who have no choice but to drive on salted roads.
In Australia , driving in seawater is viewed as silly if not stupid.
I've watched hundreds of car resto vids and even the finest of brands cannot resist corrosion.
e.g. sad to see it on a Porsche < 3years old
Do you guys have or use this sort of product?

Great to hear!
Being in the Midwest, I usually apply this twice a year or until I notice it has dried up, specially before the township goes crazy on applying salt solution on every road just before snow season.

I use a similar solution called Salt Gone.
Works pretty well too.
