well, the Perfect-It II is basically a rubbing compound. very harsh - but was needed to take the paint spots off the clearcoat.

the swirl mark remover is a lot less abrasive and will polish off the paint perfectly - ridding my paint of the swirl marks.

the PI-II is good to really clean up the paint - but is too dificult to use to remove swirl marks (the fine kind). The SMR will do the job just fine.

and it all depends on when I get my order of Z in.
Mark got his order in already - so I'm assuming I should get mine in shortly. I sent payment about 1.5 weeks ago.....
