I actually have media blasting equipment. It's a siphon feed for small parts cleaning. It should make quick work of the bed rails, then a little self etching/sealing primer and I'll be good to go. Actually I have enough primer left over, the only thing I'll have to buy is a light-medium abrasive blast material. I am also going to use Gator Guard II for the spray in bedliner. That is unless anyone on here has had bad experiences with it. I couldn't find anything bad when looking at reviews.
