6iX SPEED- Besides what the others have posted, I'll add that I've had decent results using 1z Ultra/Extra by hand, following up with 1z Paint Polish. It's not like using a machine, and yeah, it's tough work that might take a few hours, but it's something to consider. No way would I try #84 by hand, but I might consider the new formula (and only the new formula!) of #2. But if it were mine, and I had to work by hand, I'd use the 1Z stuff.
