Remove the hinges, coat the mating surfaces with something such as 3M undercoating etc or make a clear gasket from a PE milk jug. Then clean and coat the bolts with something which will insulate or possibly some spray galvanizing. The only potential contact beyond that might be whatever the bolts screw into. If it's a nut use an insulating washer. If not a nut you'll need to figure something out.
I go back to this post. If this is a steel nut not galvanized and not isolated from directly touching the aluminum door panel - you will likely get galvanic corrosion no matter what you do.
Nice job! And the bare metal factory job of all things is inexcusable. The bolts are not aluminum, I had verified that on mine. You can purchase spray zinc coating ie galvanizing paint. I used some on my galvanized boat trailer after welding up a split seam. The nut appears to be fastened to the inside of the panel. Steel?I go back to this post. If this is a steel nut not galvanized and not isolated from directly touching the aluminum door panel - you will likely get galvanic corrosion no matter what you do.
My speculations are that what looks to be rust on the nut - points to that it is manufactured from steel and not aluminum. If so therein lies the root problem. Easy to confirm with a magnet. This plus many steel bolt pins all conspire to a lot of points of contact where corrosion can progress. Add steel dust particles landing on pre-painted bare aluminum panels - and you get corrosion on the aluminum hood edge and bottom of the aluminum doors. The steel dust settles and accumulates at the bottom due to gravity. But sometimes may land and stick anywhere.
You are on the right track though. Leaving as is - ensures full corrosion progression unhindered. Most all JLs will probably suffer this unfortunate fate depending on prevailing geographical locations and atmospheric conditions. Wet and salt - faster. Dry and dusty - slower.
Speculations - but very plausible. Given how many JLs and other FCA vehicle models are affected according to the repair TSB. Please do not shoot the messenger.

I took mine to the dealership in Humble Tx, where you live. Even though I bought the Jeep in Baytown. They sent it to Service King for the repair work, and did a great job. Zero issues since it was done in September of 2021.
Interesting. When I took mine to them (in Humble) in December they said that they didn't have a body shop and that I should try to find a Jeep dealership that did. Currently, the other dealership has sent the photos of my paint/corrosion issues to FCA, just awaiting to hear back.
They said the same thing at first, but when asked about how they fixed cars, that were wrecked, they said they send them out. I asked they treat me the same, since it is a.warranty issue, and I shouldn't have to drive.all over, looking for a dealership that does bodywork. There was a female service advisor giving me a hard time about everything, and pissing me off. I told her I wouldn't deal with her anymore, and to get a manager. They switched service advisors, and things went smooth as glass, after that. Since then, I only deal with Dalton(first name) and he will do what it takes to help customers. BTW, several people, and manager apologized for the female service advisors attitude. She has a history of this.
Correction. Feb. Of 2021. Well over a year ago.
Thanks for the heads-up. I dealt with Dalton on my first visit. Nice guy, but also the one who suggested I find another dealership for body work. I'll press further in the future. I'd rather not drive an hour for service if possible. BTW. I had that same Service King (probably the one across the freeway from them) do some work on an Accord a long time ago and they did a great job.
Huh? Nearly 150 pages along with a few other multi page threads related directly to bubbling around door hinges. Every story here is the same, dealers trying to avoid the situation because they know it is larger than they'd ever admit. The "only on some" hopefully was directed at individuals like yourself that aren't going through crap paint jobs.
Yep, that is what I mentioned. As I said, I don’t know why mine don’t have the issue. But I am glad that I don’t. But I guess, that it could still happen in time.
I do not see how it could NOT be an issue. After looking at new Wranglers a couple of weeks ago, one can clearly see the bar metal behind the hinges where the paint did not flow. Admittedly, I did not bring a magnet to test the metals.
I don't know if anyone knows this for sure. My Jeep is about to turn 4 years old at the end of the month, and I never saw any bubbling of paint until this spring. So maybe in a few years the newer JLs will experience this too?
My Jeep did spend a lot of time parked outside in the past year, and it was more than the previous years.
