My experience with rubber on metal is mostly on the whirly birds and some on wing deicer boots. The door seals are rubber and the manufacturer's put them on with contact cement. With time and heat from sun baking, the contact cement becomes brittle & cracks. After that the corrosion starts and the seals start to fall off. I have spent hours removing the cement that wasn't affected in order to keep from ruining the door's outer finish. A person wouldn't think that aluminum could corrode so much but you would be surprised how bad the exfoliation can get. I had one machine that an operator spilled Coka Cola on the seat and door frame & didn't do a very good job of cleaning it up. That cost them a pretty penny to repair the damages from that.
If your vehicles are kept from being in the elements then it should be a lot less of an issue. If the vehicle is left out in the elements it will suffer. The steel corrodes just as bad or worse than 2024 aluminum in that case. This is where the vulcanizing was important. FoMoCo had a lot of experience with running boards before they went to that process. I'm sure that played a part in the decision to go that route. That is how I would do it as long as Hunley is still around. The cost would not be a problem.
