What should I expect when using Finesse-It II and PC 7424?

I've used my new PC 7424 and 3M SMR over the past week or so without outstanding results. However, there are a few medium swirls that these products aren't able to remove after a couple of passes. So, upon the recommendation of folks in this forum, I've ordered some 3M Finesse-It II Finishing Material Machine Polish to address these difficult-to-remove swirls. However, I'm now getting cold feet because a few folks have reported hazing when applying FI2. I've gotten a haze when applying SMR by hand, but have had no problems at all when applying SMR with the PC.



What should I expect to see when I use the PC with FI2? Will I get hazing? Will I need to follow the FI2 application with SMR? Should I use a white foam polishing pad to apply the FI2? How safe is FI2?



Thanks in advance for your help!
 
Hey, Schwa -



My experience is:



1) Use a firm foad pad - yellow "cutting" typically. Use the orbital on 6. Work the material a long time, starting with higher pressure. It continues to dry and thin. By the time I stopped working it, some passes would actually lift the residue off entirely and (perhaps combining with tiny bits of foam) start to ball up into little grain-of-sand size lumps. This is the time to stop, and there should be a good shine - easily good enough to see how your swirls are coming. (Caution - the FI II residue is hard to wipe off. I used detail spray to help, AND I didn't try to get it completely off, because I knew I was going to follow it with SMR.)



2) When I tried FI II on the black Porsche there was hazing for sure - not sure I worked it this hard. When I tried it on the ferrari I applied as above - and there was a small amount of hazing - less than there had been on the Porsche. This could be the difference in technique or paint quality - I don't know. (BMW sprays Sikkens paint. Does anyone know anything about Ferrari paint?)



3) The above haze, in both cases, was easily eliminated with SMR - either 3M or Meguiar's.



Hope that helps!
