I stepped off the deep end recently and purchased a Griots D9, buffer. Have hand-waxed my cars for very many years.
Along that road, I had purchased a Craftsmen 10'' buffer, around 99 cause of the truck I had purchased.
Tried using it to remove the wax, and found that to be a PIA.
Jumping ahead, now having the Mustang, the truck sits in the weather and needs frequent polishing.
Having any tool one learns different ways to use them. So using the Craftsmen, tried loading the bonnet with the wax.
The heavens parted, and a lightning bolt appeared.... the machine is for applying the wax, not removal.
They will apply and spread a thin uniform coverage of wax. So the Craftsmen being clunky to use, motivated this user to find a more friendly tool.
Hence the Griot's machine, in one weekend I did the wife's car and my truck, in a couple of hours each.
A real-time saver, and no not going for the paint correction deal. I am very satisfied with the factory finish. Will use it for wax - ON, removing/buffing with soft towels.
I would not recommend using a machine on plastic panels, not for me at least, anyway, $$$ well spent.
One more thing to add, before I purchased the machine viewed some Utube videos for wax & polish brands, curiosity. Cause 3m is no longer making the past wax (damn).
Bough a few different brands to try, using on my 34 as a test platform. I have come to the reality, I believe.
Is that one brand over another, new and improved, differences seen, touted is psychological. Notice I stated brand, and not type,
I polished panels on the coupe using different brands side by side. As I went from one to the next, it seemed there were differences.
Observing the car the next day, could not tell one for the other.
