From what Im reading, people are liking AIO as a final (Chemical) cleaner just before there sealant----Just trying to get a better understanding on this stuff
To answer my other question, should I go FPII or use the 4*UPC as my polish?? Thanks
Correct. Anything that "removes" marring does it by removing some clear, so the FP does that, but it takes off so little you'd have to use it every day for years to cause any problems. Unless you're using a harsh polish all the time it's just not an issue.
