Flex XC 3401 VRG vs. Porter Cable 7424

this is not a fair comparison...for a fair comparison find a forced orbital like the makita bo6040

can i use only the 3401 for car detailing or should i also buy the 3403?? Somebody said the 3403 is for removing deeper scratches and the 3401 for swirl marks??

Thanks for the video!! I am a mobile detailer in the Tampa, FL area and I am looking to upgrade my polisher. I have been debating between these two and your video really made my mind up to go for the Flex polisher... THANKS!!

Why do you say this?

Simply because the lower power of the PC makes it a safer tool for the beginner, is $150 dollars cheaper (that's quite a lot), and speed is not as big of a deal as if you were a for profit detailer.

Wow, I didn't know that even with a machine that polishing takes that long. How do you know when to stop polishing though? It still looked as though there was still product on the car.

The product will "flash" or turn translucent. The should always be product left to remove, if not you are basically dry buffing and just scratched up your clear coat.
Also machining buffing by a real pro can take any where from 5-7 hours to do a full exterior detail depending on how bad the paint is.

max 3000 rpm. Most dual action machines will not go past that.

but those polishers can only polish in circles right? what about those with the up and down rotation, are those better and ive heard that you dont see the swirl marks from the machine after the polishing. Here in germany the ppl like Festool Rotex and Flex products.

LOL!!!! One of these is a Flex product, read the description. And these are random orbital buffers, not rotary. ^^~
