well, lots of sanding later an 90% of the tub surface is now bare metal. Unfortunately the last 10% will probably take as much or more time than the first 90% lol.
At least there haven't been any hidden surprises yet, truck has never had a re-paint and hasn't had any real body damage other than what I already knew about (a dent in a crappy spot on the body line beside the fuel filler, a dent under the driver's side taillight, and two dents on the roof). The only other issues so far are a couple of small dings & dents and a broken spot weld on the drivers door.
