Sliding brake hoods
My Carlton hoods slide forward on the Weinmann levers when I rest my hands on them. Any way to stop this?

If these are the hoods...
...then, consider them to be poorly designed - get a set of Weinmann gum hoods that fit better. That said, find a way to shim the hoods, on the rear of the brake supports. Perhaps try stuffing some silicone seal in there and hope you never have to remove them. Other than that, I can't offer much.

They have probably dried out over time and become hard and slick. Best bet is to find some compatible replacements.

I suspect that back in those times, the design interface between levers and hoods, weren't done so closely but was only based on a just a couple of measurements that just assures the hoods would at least go over the lever body without tearing.....
Thus the sloppy fit of those Carlton levers.....
Maybe you could just wind a layer of bar tape on the lever body to thicken it up to make the hood fit tighter. You can use one of those grippy tapes made by Fizik to also help the hood gain some "traction" on the lever body and further prevent it from moving around.....
You might check out Cane Creek hoods too, but I noticed that the fit on those for some levers can be quite poor too....

Bikes are okay, I guess.

A little solvent may make the hoods tacky on the inside. Perhaps that would work.
Fwiw, Velo Orange has replacement Weinmann hoods for sale. The Carlton hoods are not very comfortable, but extremely tough. If there is ever a nuclear holocaust, cockroaches will crawl out from under Carlton hoods.

The white Carlton hoods were made of some kind of plastic, not rubber. They've survived for over 40 years!
Maybe the aluminum levers dried out and shrank?
Kidding aside, I'd try rolling the hoods back enough to wrap some cloth tape around the lever bodies. That stuff was designed to be slip resistant on the bars so it should easily fill the gaps under the hoods and reduce the tendency for them to move around.
Duct tape - "Spare the tape - spoil the job!" The Red Green Show!

Remove them and keep aside for original/era purposes. Get a set of the Rustines gummies. They snap fit like a set of surgical gloves and look great, not to mention feel great. What, 23.00 the pair? Good deal. I have them on the Colnago and looks like they will fit your application.

If you can remove them, and re-install without destroying them, I'd use double sided tape on the lever bodies. Or even a coat of rubber cement.

I have found these hoods only semi flexible.
I would remove them, probably by taking the lever body off the clamp with the cables out and clean them. These hoods don't really outgas plasticizers much but the material is semi permeable. Maybe some spray lube directed at the lever internals migrated via the clamping cross rod. Clean them up well and rinse, clean up the alloy. It would not surprise me if the inside of the hood is quite grey or black from the alloy rubbing.
I would be tempted to introduce some adhesive to the inside top of the hood and lever body. Something compatible with PVC, which I think these hoods are a version of.
