Ok. But maybe I didn't make my ultimate goal clear- to spray something on car that will leave some kind of barrier or film so the playa dust sticks to it, not metal, and can then be more easily washed off. I thought of even something like armourall, wd-40, tire shine or something like that. Have you seen under the hood of a car after used car lot details it? They spray everything down with an oily armourall type stuff so it looks all shiny and new. It's also greasy to the touch, leaving quite a film behind. Am I chasing a white rabbit?
I know enough to know I don't know shit. I just wish more people knew that much.
