Ok, I just bought #1 medium-cut cleaner, #2 fine-cut cleaner, #3 machine glaze, and #7 show car glaze. So I have told ya'll in the past that I have a 98 mustang GT that needs "JESUS" !!!!! It looks like it was washed with a SOS pad... So is a #1 the same as #83??? Or is #2 the same as #83??? Or are they all different??? And witch one sould I use on the car first???
