I have been throwing the idea whether or not to sand blast my jeep. Since my tub is only bad in a few areas like rockers and where the floor pan meets the tub, i need to effectivly undercoat the chasis and body. I was thinking of some duplicolor rust fix in some bad areas and just using a primer/sealer and rustoleum undercoat on the frame. I was thinking about using duplicolor bed armor on the tub and seam sealer where needed. What are your opinions? I know cut and welding are in the very near future but I would like to get as much as i can now. I am looking to do this this weekend with store bought material if I go this route.
