I am restoring a 66Chevelle. the frame is complete. About ready for the body. Blasted, rust converted, rust encapsulated, and Eastwood satin chassis blacked the frame. Blasted, rust converted, rust encapsulated the body. what do I need, to do to the firewall and underside? Chassis Black, enamel, polyurathane? I want a very durable finish. Do I need to Epoxy seal the underside first?[ATTACH]4021[/ATTACH]
