I believe he retired his Makita in favor of a Flex PE-14 rotary. I didn`t interpret it as bowing to corporate pressures, but who knows. I don`t know what he likes to use on those oxidized gelcoat boat hulls these days.
I have one of the first Flex XC 3401-VRG machines purchased many,many, years ago. Even before they finally came out with the 5" backing plate, which I purchased, and this alone made it more easy to handle.
Getting used to the counter-clockwise rotation was the only challenge but I got it just fine..
Purchased it to see if there was finally, something that would work better than my Makita 9227 Rotary, and after a few tries, the Flex could just not be leaned down on and still work like the Makita can, no matter how much you lean on it.. And then there`s the vibration that would put your hands to sleep after a few hours which I didn`t like either.. Makita = smooth as silk at any speed..
I also purchased the Flex PE 14-2 150 rotary and while it was pretty powerful, it was not as heavy, so I didn`t have the extra weight on the machine that I like to have handy, and it made a lot of gear noise, so it`s not as quiet as the Makita.. And lastly, the Flex rotary does not go to 3,000 which is the best speed to get all the water out of cleaned and rinsed pads quickly..
The only machines that last the longest on boat gelcoat grinding according to my best friend ultimate boat Detailer in the Pacific Northwest is the biggest Dewalt they make.. He has had a hand in consulting with Dewalt because he uses so many of their rotaries in his work, and even with all the things they implemented to help their machines work better, last longer, etc., they still do not last long before his Team wears them out..
And I have seen his work on black boats and the finish he gets with that big Dewalt is pretty much as good as the perfect finish I get on all Jet Black Bimmers..
Another reason why I will never Detail boats either..

It looks to me to be about as miserable as grinding on that nasty rock-hard urethane airplane paint, which I also will never do again..

Happy New Year !
