Tom,
have you played with one yet? I was going to ask about that during the Doors class and forgot.
I haven't used a direct rotary buffer since mid 80's. Is it quiet, smooth? 4.6lbs, pretty light.
I see it looks pretty similar to the Flex, but I like the idea of the speed adjustment on top as I'm left handed.
I remember that a direct rotary was easier to burn a paint job if not careful, but I liked it for acrylic when it hazed.
I know the polishes are refined to make life easier. Of course, I only have base clear coat, what you buy from factory,
I don't paint stuff anymore, just polish my autos.
TIA,
Jerry
