I've had great luck and gotten compliments with using a PW to wet everything and pre-rinse (stay 1.5 to 2 feet away with the nozzle), spray some APC or any other degreaser, let it dwell 5 minutes, agitate with a soft-medium brush if necessary, rinse with the PW (same distance), dry with a leaf blower, spray CD-2 all over (follow can directions), and smooth any CD-2 drips later if necessary. Ends up looking fantastic.
