This for me is the most frustrating part of owning a tracker. living on the east coast we get alot of salt not only from the atlantic but also from the road ways that are white long after the snow melts. I rebuilt my tracker last year and it's already rusting out again. From the two trackers I rebuilt, I found it's the rockerpanels, the floor pan and the front fenders next to the bumper that rust out the quickest. I spray lined my second kick the first week I got it. worked like a charm. I honestly don't understand why it's so hard for manufacturers to make a washable interior (with a hose) and plastic body panels like a saturn or something. I mean they know that the truck is gonna go somewhere sometime in it's life...  but then they can't make a car that'll last "too" long .. :-/
