Engine compartment color

Yep. Get in there, remove front bumper mounts, expose the frame. Rent a pressure washer if you don’t have one and pressure wash everything. Then go back and wire wheel everything to metal. Or whatever means you choose to do so. I spray with starting fluid and compressed air to clean the surface. Then I spray with rust inhibitors. Then new undercoat. You can spray that if you like, but it is already black. Very time consuming process....not quite done in first pic. See how water just beads off in second pic after blasting again? That area in the front is paintable after sanding too. I’m sure someone will tell me I’m doing it all wrong...lol
