This is sort of a hypothetical question since I really don’t wish to spend this much. But:

I take a wide variety of photos but this would relate mostly to my nature and wildlife work. I am quite shaky in holding and end up with a lot of blurred photos. Some background. I’m 87. I have never been very strong, more the 97 pound weakling type. For years I was fine but as I got older I got shakier. I compensated to some extent by heavier equipment. (A Nikon 7100 with aux battery box,and a L-bracket.) I found the weight helped dampen my shaking to some extent. Then VR came along and I bought some VR lenses. That also helped. But as I get older I also get weaker and I find that the increased weight is as much a hinderance as a help. On top of that I have, the last few years, developed Essential Tremor where my hands shake. This is continuing to get worse with time. So, I am looking for a solution. Please don’t say tripods, I bought my first tripod, a Linholf, about 1956 and I now have tripods everywhere. The same with monopods. And a piece of string attached to the bottom. Etc. It’s not my type of photography, plus it’s more weight. Anyway, my thought is, if I should buy a Nikon Z6II, and also continue to use my existing Nikon lenses with VR, would the additional VR in the camera body make a noticeable improvement in optical steadiness?

I recently acquired a Nikon N90s camera. The back ( MF-25 ) was very sticky as was most of the camera. The camera works fine and I decided to see if I could restore the finish on it.
Materials used - alcohol- above 90%, paper towels, ArmorAll, automotive car wax, micro fiber cloth.

It is fairly simple process. Use the alcohol to remove the sticky coating on the back, lots of rubbing and changing the paper towel often. Then clean the rest of the camera with alcohol to remove the migrated coating from the rest of the camera.

Once that is done, I sprayed some ArmorAll on a paper towel and wiped down the entire camera. Remove any residue with a clean cloth.

Now the camera is nice and clean and no longer sticky.

The final step I used is to put a coat of automotive wax on the camera. Apply the wax, let it sit for a few minutes, then polish the camera with a clean cloth.

Some cautions:
don't get and cleaners on any lens, it you have one attached. With any liquid, spray on a cloth or paper towel,
DO NOT SPRAY DIRECTLY ON THE CAMERA.

The N90s had some printed information on the back. This was removed as part of the cleaning process. I have attached some images showing what they looked like. I have no way of restoring this information, They are white and even if my printer actually printed white, I would have no way of getting that back on the camera.

This whole process took less that an hour and I now have a like new camera.

Unless you're quite old, or if you have worked as a photojournalist, the name Gordon Parks, Sr., probably won't mean much to you. But if you are an American, and especially an American of color, his work is something you will be glad to know about.

I met him just once when I was a very junior Public Information Officer at Fort Benning in 1967. I was escorting a couple of guys from National Geographic and we had lunch at the Officer's Club. Seemingly out of nowhere, Parks appeared and was invited to join us. I knew who he was, of course, because my road to a commission and a job as an Army Information officer had begun with nearly a year as a combat photographer with the justly famed First Cavalry (Airmobile), and this had brought me into contact with a who's who of the world's finest photojournalists.

Even before that, I spent half a year of evenings in libraries looking at back issues of America's best photo magazines--National Geographic, LIFE, Look, and Pageant.

The most important thing I recall from this chance meeting was that Parks had decided that print photojournalism was walking dead. He had enrolled in film school, and it was his intention to make movies. Which it was and which he did. And more's the pity that weekly magazines like LIFE and LOOK and PAGEANT no longer publish.

Anyhoo, here's a little peek at Gordon Parks and his work:
