Maxter,
I would use the paint cleanser as a way to prep the surface. Then just use the applicator from S100 to apply the wax in a linear motion back and forth like the air flows over your truck.
Do small sections and buff out before it hazes completely. I find the PakShak MF ultra fines are superb for this but any quality MF will do the trick. Actually I use a midgrade MF and then final buff is with the PakShak ultrafine or David's Autopia CBT.
You may also want to "clay" the vehicle for the best possible results. Autopia has a great article on this if you want a tutorial. Also visit

Best of luck...this wax is awesome on silver cars! :xyxthumbs
