How is rusting down there Sean? I worked for a company that built Industrial playground equipment. We had a lot of problem with the stuff we sent to the coastal areas of Florida. Everything had to be stainless steel and aluminum, and it still rusted or corroded pretty badly.
Here's what I can say from experience. Up North, the bottoms do rot out of cars...but oddly, it was more prevalent on the cars that people washed weekly in the winter, not the ones who let the dirt and salt set all winter and give it a good once over in the spring. At least, that was my experience. Now, some of the chemicals they use on the road, in lieu of salt are way harsher though.
As far as cars in Florida, Sean, you probably have more experience, but unless you are really close to the coast, or you frequently drive your car in the Gulf or Ocean, Salt isn't a huge issue. Actually, experience in installing alot of railing systems in Florida along the coast has shown a few things where S/S and Aluminum are involved.
1) most stainless fasteners that are used with Aluminum (in our industry anyway) are 410 Stainless...which really doesn't have much corrosion resistance. Large bolted assemblies may use 316, but that is rare.
2) Aluminum reacts with Stainless steel, so adding even a little salt to the equation really kicks that anodic reaction into high gear.
3) Sand-actually, alot of times, you have the wind blown sand that acts as nature's little sandblaster...it takes the luster and paint off stuff given enough time. So, the salt doesn't attack anything until it gets through the paint...then you gots problems.
