About 95% of the undercoating is off courtesy of propane and propane accessories, along with scrapers and picks!
The next phase is the wire wheel on the grinder followed by a chemical wipe down to dissolve the remainder of the nasty goop. In the crevasses, a spot blast gun with some good ole 60 grit slag to get into the nooks and crannies.
Should be 'rollin phat in epoxy shortly! Couple small areas I will have to break out the hammers on. A pushed in floor corner and the driver's front frame rail shows some pretty good jack damage.

But fear not! It'll be fixed poste haste!
More to come....
Cheers
