Re: 68 GMC 4x4 chassis being built to be a 70 4x4!
Mike it's definitely a "process". He wanted to get all the pickling solution off the rockers and cab corners and floor first so that's why he blasted them so the epoxy primer will stick better. Now he'll weld everything up, blast some areas again including all the welding seams and then shoot another round of primer.
