Okay i know there are probably a million threads about cab corner rust. However i am looking for some advice on my specific scenario. Basically i have a well kept 2004 F150 that is just starting to bubble up in the cab corners. The truck only has 77K miles and mechanically is in tremendous shape. I only plan on keeping the truck for another year or so before i upgrade to a new truck. What is the best short term solution to lessen the spread of the rust. I don;t want to sink a bunch of money fixing rust, but i would like to slow it so its next owner can address it before its too far gone.
