The process I've been using since '06.
Since I'm not yet using exclusively poorboys products (I will be soon as finally running low of other products! :smt035) someone will have to chime in on the best available PB cleaner, and post dressing.
-Have engine warm, not hot.
-Cover delicate electronics.
-Lightly wet down areas to be cleaned
-Degrease
-Rinse (blow dry optional)
-Start and run to prevent water drying in areas.
-Finish with a water based (ideally) dressing to prevent rubber and plastics from drying out.
The plastics were neglected too bad to clean up perfectly on this engine, and were so dry I told the client we had to apply the dressing twice.
I know you probably just needed to know what PB's products to use, which was about the only thing I didn't answer Shawn haha. Wanted to help anyone on the process till someone can chime in with those answers.
