-AND-
You no sooner agree with me...and now I'm gonna change my tune! Well, maybe, sorta.
Noting that I have more experience with the 1Z HG, and that I'm comparing the results on different vehicles, and I'm switching from doing this via Cyclo to doing it via Flex, and that I don't do enough correction these days to, IMO, really have a decent knowledge base (gee, after all those qualifications what's my opinion even worth?!?)....
I tried a different burnishing routine with the M205- Flex/LC 7.5" black/speed "4", no real pressure after the first two motions across the area. Moderate arm/machine speed.
Turned out very nice and I'm sure not gonna bother trying to improve things by trying the 1Z HG. Nice and quick too, much quicker than the 1Z. Did use more pads and product though.
Eh...both are good but I'm sure finding the M205 to be a lot more time-efficient. I'm going from 6" *Griot's* orange to 7.5" LC black and getting a lot done with minimal work in a short period of time. So far so good...
Some day when I don't mind spending more time on this stuff (yeah, keep dreaming kid...) I do want to try burnishing with FPII. Guys like SuperBee364 have me convinced that it might make a little difference.
