I had trouble keeping up with all of the different posts. I did not understand how/if/when you stripped the entire cab.
I prefer media blasting and epoxy priming in order to get to all of the areas which are hard to get to any other way. It wouldn't be that much trouble for you to blast just that area which you are having issue with.
