Stop in for a cup of coffee

So, after I paint the chassis on the Charger, would I use Slip Plate or Fluid Film to help with the salt at Bonneville?
I have only used it on bare or rusty metal. I just put it on a rag (wear rubber gloves) and rub it on and kind of buff it the same time. Basically, graphite so it doesn't burn off at all. Do not get it in a spray can the nozzle clogs up right away. A qt will do dozens of slant manifolds, goes a long way

Fluid film would work the best. Get a sprayer for it. They sell kits on flea bay.
