Here's a little something to help you get on the right track. Its the relative abrasive level of Meguiar's products.
#85 Diamond Cut = 10
#84 Compound Power Cleaner = 9
#4 Heavy-cut Cleaner = 8
#1 Medium-cut Cleaner = 7
#83 DACP = 6
#2 Fine-cut Cleaner = 5
#80 Speed Glaze = 4
#82 Swirl Free Polish = 3
#9 Swirl Remover 2.0 = 3
#3 Machine Glaze = 1
They don't list anything at the 2 rating that I know of.
One of the reasons that DACP is so highly considered on Autopia is because it is a nice polish that lies somewhere in the middle of the scale. The abrasives break down durring the process and make an effective polish on all sorts of damage. I love the stuff. I've used a lot of the 3M line, and just like some people prefer Coke over Pepsi, I prefer some of the Meguiar's products over 3M (I'm also a Pepsi guy.
). DACP is one of the good ones that I really like.
