David,
I think this product is for manufacturers who use extraordinarily hard clear coats (i.e. scratch resistant)--but the new infiniti "scratch shield" clear coat is extroardinarily soft "gel-like" clear:

Danforz,
I agree with NotZeroSix that using your new G35 as a test different polishing techniques may be a risky move. The idea of this new clear is that small swirls will "heal themselves" over a few weeks. The infiniti EX has had the new clear since 08 (I believe), but the rest of the infiniti lineup got it this model year.
Since I have a new 09 M35--I'm hoping some of the pros here will figure out the best way to work with this new clear--without it "coming off in little balls" on the PC pads!
