Scotty, I've been spraying silicone on the rubber seals of my cars to keep the rubber from freezing to the metal and freezing me out of a way to work in the morning, but I don't know if this is the best thing to use. I do know it only works for maybe one or two bad nights. A friend is using Vaseline, insisting it does not damage rubber (it does), and that silicone will damage rubber (it does not). You can't use petroleum products on rubber—it degrades or even dissolves it.
What do YOU use?
I've been spraying silicone
I find that the aerosol stuff has no staying power. It evaporates overnight and it's gone!
I just applied brake grease to my seals about an hour ago (it's silicone. Safe for rubber). I take a small rag, saturate it, and then work it into the rubber. Wipe off excess so it doesn't attract dirt.
I've been using if for years. It works well and as a bonus it makes the rubber soft and supple, and keeps it from drying out. Dielectric grease will work too. It's basically the same thing.
It's a little cold to apply it now, but waxing the painted inner part of the door jambs and the sealing surfaces of the metal doors helps keep them from freezing shut. The water beads up on the finish and freezes in beads, instead of sticking to the pores of the paint and the rubber gasket.
good ideal . wax seems less messy too.
I wax the insides of the doors on my Mustang because it keeps dirt from building up and it really looks great at car shows. I've seen competitions come down to door jambs cleanliness. Haha. I think the biggest concern is keeping the wax off of matte black plastics. If you get it on there, it looks like you wiped oil on the part
Baby powder.
Interesting idea. Does it get imbedded in the rubber?
I think it just absorbs moisture, and makes things slippery. Similar to how gymnasts powder their hands.
Rub a hand full into the door seal.
Have you tried WD-40?
wd40 degrades rubber
UP HERE.....WE USE WHALE OIL.......
... and all-caps too apparently
