I do not think in Florida the problem is as critical, but still needs to be addressed. I sprayed WD 40 in the area just to be safer.
RMADERMAN, speaking as an X employee of B.F.Goodrich, from what once was the "Rubber Capital" of the world. Rubber and oil don't mix, unless it's neoprene. WD 40 will eventually dissolve your rubber seals and turn them into a "gooey" mess. Use a silicone spray (if you don't want to make the now famous, "Drew Repair").
The rusty door problem is universal, it doesn't matter where you live. Water and exposed steel is going to oxidize, with or with out salt.
I do believe the problem was first brought to the forums attention when somebody from Arizona posted photos of their grey cars door rust. I can't think of a more arid place (in the U.S.) than Arizona.
The "untreated" cars that are going to start rusting first IMO are those that get washed more often, and or, the cars that have to sit out side in the rain.
Sorry for the thread hijack.
