Just bought a '98 Cheyenne for a work truck that I'm pretty happy with, appears to have been driven mostly highway miles around here (Midwest). Most if not just about all of these trucks around here develop the rust-out over the rear wheels. What is the cause/prevention for this? Has anyone ever drilled through the inner fenderwells to get to that area in between the walls of the box and blasted a bunch of undercoating in there? Seeing so many of them rusted in the same spot would suggest there's nothing can be done about it, but it seems like if a person took the time they could at least slow it down a lot. TIA
