I think that era GM had trouble getting paint to stick their cars period. Had to do with the galvanizing they were using on the steel or something.

From my understanding, there is no actual adhesive in the traditional sense. As long as you keep them flat they should be fine. If dirt sticks to them, rinse them under cool running water.

There have been several people here, myself included that know this stuff does not work

Here is a link - we've used it - make a print using the vehicle color - adhere to the car and apply your magnet.

It actually does work really well if it doesn’t rain, getting water behind it can be a problem.

You should disclose this when you mention this product because most people live in areas where it rains and this is not a viable solution to vechicle magnets.
Kind of defeats the purpose of a magnetic, doesn't it?

It’s all about your print!
Doesn't this defeat the whole purpose of a magnet? We tell our customers, if you're not moving it around on a weekly basis, minimum monthly basis, you probably just need a sticker. Amazing how many people end up ordering stickers because they didn't realize they can get them off when they sell the vehicle! (With the right material of course, and time.) Customer Perceptions - Stickers: Permanent, Magnets: Removable

The same way they keep the vehicle clean. They don't.

The applications where we used this method was that of trucks with fiberglass or aluminum doors and in particular where a trucker was driving for different companies. He would replace one magnet with another depending on whom he was employed - it actually worked out for him... other than that we used it in an application where the customer had aluminum panels mounted on a wall and wanted magnets for production work that had to be moved around. We laid the rubber steel on the the aluminum, overlaid printed/laminated vinyl with his work flow diagrams and then made him a bunch of smaller magnets that could be re-arranged on the board. It worked out for them too. Other than that, I do agree that it defeats the purpose of magnetic material. Hope this explanation clears things up.
Apparently these Gripper Mats work quite well. https://properdesign.uk/products/new-gripper-mats-magnetic-sign-grippers-for-aluminium-vehicles

I wish I would have saw this thread. I had the same problem same truck also. Luckily my client said they were going to buy a new cargo van soon and that they will use the magnets for that vehicle. In the meantime I provided them with a couple of low tack vinyl film sheets. They said that they Will only use them once for one day doing the month maybe twice during the month for only one day. I told them to store the carrier make sure that they clean the doors etc. They were fine with this plus they still received the magnets that they could use under new vehicle. However someone in this form brought up the option to use coraplast. I think I like that idea better. If I would have saw this form first I probably would have went with the coroplast for temporary signage in place of the magnets.

This is EXACTLY what I was going to suggest, but instead of really strong magnets, I was thinking just stick strips of 3/16" 409 (magnetic) stainless steel to the inside of the door skin (horizontally) using a product like 3M 467MP.
