i HAVE SOME RUST HOLES IN THE BOX OF MY TRACKER.jUST OVER THE WHEELWELLS UNDER THE BOLTS FOR THE SEATBELTS.cAN ANY ONE TELL ME A QUIK AND LASTING FIX FOR THIS.i WAS THINKING RUST INHIBITOR AND SOME THICK BOXLINER COATING???

I've heard of people using rust inhibitor and then covering the hole with duct tape followed by a thick layer of bed liner material.  However, if it's anywhere near the seatbelt bolts I would recommend an all-steel repair since a life could depend on it.  HTH.

I would definitley cut out all the body rot and weld new material in. You can buy nuts and weld those back in for the seat belts, at least that's what I did.
I have my kids riding back there so I wanted everything good and strong.

I know a couple of guys who should 'cause they lost theirs to their wives. 

I have no rust even close to the seat belt holes.It was all on the bed right under them.So I cut out the rust put some sheet metal down and riveted the metal down.Then I caked the s--t out of it inside and out with some black tar under coating.I also used the rust inhibitor.
