WOW! Thats almost the same system I use.
the Mr. Clean works pretty well....still need to keep an eye out for drips and puddles, WRX's have a lot of little nooks and crannies that can be a real PITA.
I've found the STP tire shine to be the best.
nice dull shine....doesnt attract dust like the other products (macguires).
I gotta say.....I figgin dig the new detailing forum
