Assuming you are working on Ford paint by machine, chances are you won't need the RD3.02 or 85RE; in most cases, a single stage process using 203S on Menzerna polishing pads will correct Ford paint to a very high standard, with no need for a subsequent refining stage. Also, the wash products you list can be bought as a kit with 10% off; see here...
