depending on what level you are going for. The easiest/safest method that gets good results, is a DA or orbital polisher (you can sit it on the truck forever and never burn through), a compound like System One X3 or Megauiars Ultimate Compound, clay the truck, then polish with one of those, then hit it with a wax....obviously if you need to cut more than that, then a rotory buffer and 3M or Meguairs cutting compound, followed by polish then glaze/wax will do the job, but be very careful not to burn through the paint!
