Makes sense, interesting. I learned of this years ago in the seventies when I worked at my sisters detail shop. We did a lot of cars for a few nearby dealers and one of the services was those rivet on mouldings that were so populer. Yes, I am one of those jerks who drilled holes down the side of cars that you guys are no restoring!
Anyway, these mouldings had a rubber insert. After the aluminum was riveted on you cut the rubber to length and slid it onto the aluminum mouldings. You could easily see the ones that were done wrong, after a few months they would shrink and the rubber would be too short for the moulding leaving a little gap at the end.
We had a hot water heater that was turned up real HIGH and we half filled a five gallon bucket with this hot water. After cutting the rubbers an inch or so longer than the aluminum moulding we put them in the hot water for a while. You could pull that baby out of the hot water and stuff it on the aluminum mashing the too long rubber in to fit. It was very easy being it was so pliable. When it shrank a little with age it still fit well.
But putting these rubbers in without the hot water......it was a MUTHA
