I am in charge of the parade committee for my fire department. Currently this is how it is done: Wash with zep wash+wax combo. Commercial wash we get in a 5 gal pail. Dry with water blade. Use Final inspection over the entire surface. Polish all chrome with mothers chrome polish (also use on stainless) Apply tire dressing to tires (spray on). Things I'm looking for: A different tire shine I saw a few trucks at the convention today that almost looked like somone had coated the wheels with a clear poly very different from your run of the mill tire shine. A good metal polish for diamond plate. Currently we are using flitz for the diamond plate (2 trucks will need a good acid wash to get the aluminum back to polishable shape). IMO flitz seems better than mothers mag and alum. Any suggestions on the way I'm doing things and products. You have to remember what works on a car might not be so easy to do when your working with a truck thats 35x11x8.
