Calling Todd.....again....

There are MF pads being released that claim they can be used with a rotary. Well, my first thought is that with the *forced rotation* of the 3401, the MF pads don't work well at all, IME. On the same note, a rotary is forced rotation as well. Does the forced circular motion of a rotary work better with MF pads than the forced random orbit of the 3401? If I had to guess, I'd say no, but I'm not sure, that's why I'm asking you. :rockon

I was rather surprised to see the new pads being recommended for rotary use as well; what I'm wondering is if the nap of the fibers is thicker, combating the effect we've seen happening on our 3401s....

The micro shine polishing pads(exact same as optimum, IMO) I have, the MF either is thicker or fluffier. If I had to guess, I'd say it's the motion of the 3401 that doesn't jive, rather than the MF, but I'm not sure??????

Hmmm Mark... Once again you put me on the spot.

There are MF pads being released that claim they can be used with a rotary.

You can use any microfiber disk with a rotary polisher, should you desire. The rotary is going to move the pad with significant speed, and provided the pad creates friction on the paint's surface, you are going to achieve some level of cut.

So I don't see why you couldn't use these discs (or any other microfiber discs) with a rotary, but I do question, given the pad's design, if this is the most effective use of the disc.

Well, my first thought is that with the *forced rotation* of the 3401, the MF pads don't work well at all, IME

The MF design is going to work best when a fast orbital action will constantly expose different sides of the microfiber to the paint. If the microfiber is evenly coated with abrasives you are benefiting from a HUGE increase in the amount of abrasives that are actually working in a time-frame.

When the pad is spun faster, centrifugal force is going to pull the fibers outward and create a flat disc. This reduces the benefit of the orbital motion, and kind of leaves you in limbo.

On the same note, a rotary is forced rotation as well. Does the forced circular motion of a rotary work better with MF pads than the forced random orbit of the 3401?

The rotary is going to be the king of creating friction on the paint's surface, and its ability to drive the pad a high speed across the paint is going to make up for some/most/all of the short comings of having the pad lay flat as on the 3401. I would assume, with out ever testing the two, that the Random Orbital is going to give you the most correction in regular use, the Rotary would be second, and the Forced Rotation DA is going to be third. That said, if you turn the speed up to 3000 RPM with a rotary and lean into you will be make just about anything cut.
