1968 Dodge Dart GT Sleeping Beauty?

Back in 2008 I did my engine compartment body color with custom mixed cans of spray paint. Looks great but lacks the durability of 2k paint, chips scratches and stains easily. Since then I did a bunch of other engine compartments 2k paint and detail gun. Detail guns don't require as much air volume and atomize paint good for shiny finish. Most recent engine compartment I did, 2k paint, brake fluid leaked on it and no effect on the paint.
