Started thrashing on the frame since it's exposed. Lots of wire wheel work here. I hope everybody who does uses an angle grinder with any attachment wears PPE. A wire wheel cup worked best for us.
The chambered exhaust was kinda cool for awhile, but loud. Going much quieter this time around. My muffler guys assure me that we can sew any type muffler right in line with these. That'll happen once it's back on the road.
We then put the POR-15 on the frame, springs, rearend, everything from the underside of the cab back.
We learned later that being ambitious on the frame this early in the process isn't necessarily a good thing. Primer and sealer along with the normal bodyshop environment will cause you to re-do things. Fortunately, we needed to put POR Chassis Black over the paint, so it wasn't wasted time.
