[67C10Step]

I posted this photo in the what did you do to your truck section but these are brand new parts from Mar K and were bare metal. Scuffed with 80 grit, cleaned with water based cleaner, cleaned again with SPI solvent based wax and grease remover, and then sprayed with SPI black epoxy primer.
All I will say is if you think your body guy is charging too much ask him to let you lend a hand in prepping parts. I know I have 8-10 hours total in these three parts sanding, cleaning, prepping, spraying, and then cleaning up.
