1) Just use AIO. It is senseless to use PPCL then use AIO afterwards when AIO is more aggressive.
2) Since the consensus is to only go as agressive as need be for a particular application, prep with clay and PPCL, if the surface is fine, then go right to SG after a wash and SKIP AIO.
Does a new car (1 week old) need AIO? Would it hurt if I used AIO on a new car? From this thread it seems I can jump straight to SG. Should I wash (Gold Class) first and then SG?
BTW, I've got a 2002 Nissan Pathfinder, Chrome Silver Clearcoat.
