Flex XC3401VRG Random Orbital Buffer Video
I'll put one together with both the Flex and PC in the near future. I can't wait to use this thing on more vehicles, it's addictive!
My thoughts were pretty on par with Greg's review. Here are a couple of things I've thought of between using the Flex and writing the review. One potential downside is that you can only use 6.5" pads or larger. For me that is not a problem, as I love how the Lake Country pads work and finish. I know some detailers like using smaller pads to generate more heat with the PC, but due to the proprietary velcro backing plate that is not an option. Edge2k pad users would not be able to use their Edge2k system either.
I was most impressed with the power of the Flex XC 3401 VRG. I tested the waters with how much pressure I was able to apply and was unable to successfully bog the machine down. I realize I am not as skilled as Kevin (Picus) or Nathan (jedi-knight83) when it comes to paint correction with a rotary, but I have never achieved results like this with my Makita 9227C or Porter Cable 7424 ever before. With a firm grasp the unit was easy to handle and maneuver. It never walked on me like a rotary buffer but if you lose focus, it could easily happen.
The way this buffer breaks down a polish blew my mind. I personally have never seen any buffer break down Menzerna Power Gloss like the Flex did. You could have easily gone to your LSP after PG, however the ultimate clarity and depth and gloss really came from following up with the Menzerna PO106FF, especially on the black paint.
Comparing the Porter Cable 7424 and the Flex XC 3401 VRG is like apples to oranges in terms of power, control and results. If you can afford the Flex, it should be part of your detailing arsenal.
To me, the combination of the Flex buffer and Menzerna polishes are a dream come true for professionals and enthusiasts. It truly couples the power of a rotary with the safety of a random orbital. You will not be disappointed on any level with this unit.
I will post some more content as I get to spend more time with the buffer.
