Could someone school me please?

I was just curious on why you would want to use a rotary over a da? I know da's are safe on the paint and usually wont hurt it so why would someone want to use the rotary? I'm not asking to be offensive I am asking because I simply don't know the difference.

[davey g-force]

Well, DA's won't (easily) remove wet sanding marks for example.

Rotaries can do the same work in much less time.

[AutowerxDetailing]

They are able to correct paint faster due to the forced rotation spinning action. This is also the same reason they can potentially cause damage to the paint if used improperly.

So would you follow the work with a da after?

An analogy of sorts, if I may:

Here's three reasons...



Power
Speed
Effectiveness


While all the other tools have their place, when it comes time to undo years of either neglect or abuse you cannot beat the power, speed and effectiveness of a rotary buffer.


When it comes to wetsanding a car and then removing 100% of the sanding marks, you can limp along with the other tools but nothing beats the power, speed and effectiveness of the rotary buffer.

And for surgical buffing tight areas to remove defects or sanding marks it cannot be beat.

Meanwhile I tackled the random, isolated deeper scratches, some by dampsanding with Meguiar's #3000 Finishing Discs and some just using the new Optimum 3" Microfiber Pads on a Flex PE 14 Rotary Buffer using Pinnacle Advanced Swirl Remover.

Did some sanding on the cowel...


After the radiator shell we moved to an area with some raised dimples on the paint, we sanded the area flat and then removed our sanding marks.

The above is what I call Surgical Rotary Buffer work which comes in real handy for working on small or thin panels or hard to buff areas. You need an extension for your rotary buffer, small backing plates and small buffing pads.

I love the analogy lol and incredible work as always mike

[tdrake2406]

Thanks guys for the lesson. Would you recommend any videos for someone starting out with a rotary?

[Lowejackson]

I would say the DA and rotary both have a role to play. I use a rotary as I am not able to cope with the vibrations of a DA, my hands go numb very quickly

As for videos of a rotary, I am sure there a quite a few by Mike Phillips
