OXIDATION!

[CL66SEN]

I have used ACF-50 for a number of years to treat and prevent corrosion on cars, motorbikes and bicycles - everything from frames to ball bearings to moving parts. It was developed for the aerospace industry but soon made its way across into the automotive industry. I have found it to be equally effective on steel and aluminium.

It goes on similar to WD40 and a little bit goes a long way. I usually apply it with bare fingers/hands to avoid any excess being soaked up and 'lost' in a cloth.

It's easy to find in the UK, I'm not sure about USA/elsewhere, but have a look.

I wonder if they power washed the underside with a strong degreaser. That might react with aluminum. Mine is gleaming underneath and I’m at 1600 miles.

spray light aerosol lubricant ;efficient for one year at least
cheap and easy to do

Those of you have have this issue- I’d like to know where you purchased yours? I bought mine from the dealer in Pasadena, CA. It has a build date of 07/24 so not even a year old when I purchased it. Wondering if it’s random or there is a pattern?

Is the XCP product best for newer surface applications? Only asking as I’m wanting to also treat the underneath of a ten year old D90 that’s showing some surface damage on chassis etc etc
Thanks

on mine too... I did not like it AT ALL
I hate all forms of rust /corrosion and I am particularly vigilant on the underside (not many of us are...)
I have sprayed oil on the affected areas, I know it is not a satisfactory solution
I think the problem is with the alloys used

Does your manufacture date say 7/24?

Update: This oxidation is NOT surface only. It's eating all of the aluminum and there is also rust coming out of the AC Compressor. This vehicle literally drove off the assembly line one year go. The bottom of mine looks like a 100 year old barn find. If I were you guys I would crawl under your Grenadiers with a flashlight and look around!

That doesn't look to me like "normal" oxidation in the sense of aging. It seems more like it was exposed to (for example) an acid or something similar.

Under your avatar I read "Los Angeles." Even if you've never driven to the coast-line, you do have a pretty humid and salty atmosphere for a few miles inland. So maybe two things are at work here: salty air combined with a chemically damaged surface?

In the most of Southern California, salt fog ends less than half a mile from the surf zone. "A few miles inland" is a straight-up desert. Humidity is low nearly year-round.

In case anyone is interested, aluminium oxidisation is a key reason that aluminium is a preferred material in most conditions

Once aluminium is in contact with air, it quickly reacts to form a layer of aluminium oxide. This layer is chemically inert and as such forms a protective layer over the aluminium. Presence of salts in the atmosphere speeds this process up.

So a layer of aluminium oxide is a good thing.

Note, alternatively aluminium can be spelt aluminum, arguably the better spelling.
