We then applied urethane seam-seal caulking that is supposedly compatible with the PPG primer that we use.
That was a few years ago - the cab is still in primer, so this is not a real good test/report on the final result.
It seems prudent to convert the rust down-in the seam before caulking/priming? | | |
