With only a thousand or so miles on the truck, I didn't have to clean anything before application.
People have used a Wagner sprayer for FF application, but I don't have any experience with it. You may want to search to see if any settings or tips work better than others. Here's a start

Im more curious if that has been thought of before, or if it is of any real concern. I've used WD40 for my undercarriage, but those same points that i asked were asked to me, and i had no solid answer for yes or no...
I can speak about mud, but I drove though some very fine Utah dust and sand a few weeks after applying FF, and the underside of my truck looked a little like a cinnamon powdered donut. Most of the dust washed off with a garden hose and a few passes through an automatic wash with an undercarriage spray. The FF appeared to stay put after the dust was gone. The FF sites I've read acknowledge that dust will stick, but say not to worry about it.
Does Fluid Film® attract dirt?
Because Fluid Film® remains wet, it will get an initial dusting upon application, but because it contains no solvents and will not become sticky, it will not gum up or create a build up of dirt.
I'll go over it again with FF this spring to touch it up. I bought a gallon can with the undercoating gun, so it's easy to do. I'm curious to see how much rust I can find, and if the undercarriage wash did more harm than good. The difference between the areas covered by skid plates and not may be interesting.
