I was washing my Jeep today. Finally it's 38 degrees here in snowy NY. I have a 2001 and I noticed brown spots all over the body. It's like the size of a head of a pin. I hope this isn't rust. It comes off with some furious buffing with Mother's Carnauba Cleaner wax. But, I'm starting to get paranoid. I despise rust! The spots also come back in random spots. Didn't happen during the "salt-free" season, but I'll buff it off in the summer.
