Engine bay respray - progress

Mark Worman of Graveyard Carz would try to paint it as quick and shoddy as the factory did, trying to reproduce the paint splatters and fingerprints by Billy-Bob on night shift. I'm guessing that like my cars you had much rust on the firewall below the Master Cylinder. One reason I use silicone brake fluid. New cars mostly leave in primer in the engine bay and trunk, but it is a rugged primer with smooth surface (epoxy?) so looks fine. Indeed, most dip the entire body in primer so it protects everywhere, even inside the frame rails.
