I dont have any rust in that spot yet, but the latch that the rear swing gate goes into is a little rusty... Come spring i'm going to wire brush it and paint with rust inhibiting primer and a coat of hammered metallic dark gray so it kinda blends in with the paint scheme.
I have a lot of little rock chips and such on the front half of the vehicle, but no rust anywhere else. Even the underbody is pretty clean and free of rust, but that will change with time on the road here in the rust belt.
I hate rust but its something i have come to accept as every vehicle i have owned ends up rusting out even with regular maintenance and washing.
