Hi there, ok my buddie has restored a number of b body Chryslers to some of the highest standards.. what ever that is.. I have seen his work and it is winning awards for that type of workmanship.. He uses this company below and has nothing but great things to say regarding minimal to no metal warp issues, blasting off undercoat (which is generally impossible) and high rate of cut / no residual contamination of substrate.
They are in the mid west or I would have a pallet of this stuff already.
They are very friendly on the phone and can reccomend the media you need for the job.
