Rotary Buffer

[Mike Phillips]

How about the Flex 3403?

The lowest RPM is 1100 RPM and when it comes to,

1. Clearcoat paints
2. Newbies learning to use the rotary buffer

Lower rpms = better

The Flex PE14 dials down to 400 RPM the lowest in the industry for paint polishing.


There's really no need for high rpms when it comes to working on modern clearcoat paints. See page 124 and 125 of my how-to book,

Granted, I'm not the most experienced rotary user, but I'm usually around 1200-1500 RPM's when compounding. I don't finish with a rotary, so I rarely go under these speeds. Works for me and I'm a rotary noob. Just wondering what your thoughts were. Thanks.

My thoughts are everyone finds a technique that works best for them.

In my how-to book I share the precautions for using a rotary buffer with clearcoat paints.

As for me I tend to do most of my compounding on the 2 setting of the Flex PE14 which is 900 RPM. When working on gel-coat boats I will run up to 1500 rpm because gel-coat (polyester resin), is not as susceptible to damage by heat and it's also a lot thicker than THIN factory clearcoats and even thin repaints.

In the below video I used the Flex PE14 to remove 100 percent of the sanding marks in a 1964 Chevrolet Malibu after machine sanding each body panel.

The process I used was safe, effective and about as fast as a person should go when doing this type of work to this type of car.

Yes, if you use larger pads, it will get hot and it has this annoying high pitch noise.

"It" being which one?

"It" being the 3403.

I'd recommend spending the extra money to get the Flex PE14.

Mike, what makes the PE-14 smoother than any other rotary?

I used one at the Boot Camp, and I think the combination of machined gears, quality bearings and weight distribution make it so much better than the rest.
