I'm in the middle of polishing my "new" used 02 Black Altima and I just ran out of FI-II. It did a very decent job of getting most of the swirls out, but there are still some left, not deep enough to feel with a fingernail, but they're still there.



From what I understand after searching a bit, the PI line is a bit more aggressive that the FI line, 1500 grit vs. 1200 grit I believe. How is the PI FCRC for ease of use? The FI-II has been a pain to get off. I know I'm supposed to work it in, but I'm affraid of working it too long once it is fairly dry. I've been using SMR and it seems to "buff out" very easily. The FI doesn't. Am I doing anything wrong? Even when I try to wipe it off with an MF, it's very hard to get off and leaves an oily look.



Anyway, I think there is a II and III version of both FI and PI, how are they different? Is III just a new version? Does it have different properties?



And finally, should I give PI a whirl for what FI couldn't get, or am I wasting time? If I go with PI, will SMR clean up any marring, or will I have to go PI-FI-SMR?



Thanks!
 
I've used the PI-III Machine Glaze and the FCRC . . . both are much easier to work with than FI-II, IMO, with a slight downside of a great deal more dust generated while buffing. The MG seems to be a bit less agressive than FI-II, but moreso than Meg's #9. As far as how they "finish", FCRC may leave a slight haze that needs to be followed by something milder. MG leaves an excellent gloss, though, and I think it does a better job on swirls than #9.

of 3M products are easier to remove and have less residue. While I still use IHG on occassion and like it a lot, Prefect-IT Machine Glaze and Swirl Mark Remover and those of that family I have used clean themselves up, leaving almost no dust, and little to wipe up.
