Dual action better than Random orbital?

[WRAPT C5Z06]

I was told by a "specialist" that ROP's are good for spreading a product while DA's are better for correction. His answer was due to the way each type polisher spins.

For comparisons sake, Griot's new 6" polisher or 7424XP, one is an ROP and one is a DA. Is one better than the other for correction?

I ask this question because I'm trying to decide between the Griot's new 6" polisher or 7424XP. One is an ROP and one is a DA.

If you are talking about this Griots polisher then it's the same type of tool as the PC7424XP. Both will do the same job and it really comes down to personal preference. The Griots is said to have slightly more power though.

Yes, that exact polisher. Thanks. :xyxthumbs:

You can add the new Meguiars G110v2 into the mix as well. :props:

Correct.

All these tools work the same way and they work great.

Don't make things more complicated than they have to be. There's always a handful of guys, that will get so focused on a single word and miss the bigger picture.

You have a what's commonly referred to as a dual action polisher, it gets its name because theoretically the pad will spin in a circle and at the same time the pad will make little circles inside the larger many circle.

Hundreds of thousands of people have been using these tools since they were introduced to the mainstream car polishing world sometime in the early 1990's by Meguiar's.

You have a tool that is capable of create a show car finish, all you have to do is become the talent then makes the magic happen with it.

I would guess that the "specialist" was comparing the old turtle wax style buffer, and the current style of DA that we use here (PC, Griots, and Flex for example). Mike Phillips made a thread about the other style buffer recently. http://www.autogeekonline.net/forum/hot-topics-frequently-asked-questions/22208-traditional-orbital-buffer-aka-wax-spreader.html Those type of polishers are really only suited for spreading an LSP, not for paint correction.

I really don't know the technical difference between RO and DA, but the PCXP is called a DA and the Griots is called a RO. They both have the same style of head movement.

I think you're absolutely correct.

While there may be some real technical differences between the terms

Random Orbital Polisher
Dual Action Polisher

When it comes to these three tools it's really just semantics because they all use a Free Rotating Spindle Assemble to move the pad.

Mike,

Sorry for digging up an old post but I think it would be nice to share some information with members of Autogeekonline.

I just did a Google search on this topic and found a post on another forum which some of you might be interested:
TheSamba.com :: View topic - What's the difference between dual action and random orbital (http://www.thesamba.com/vw/forum/viewtopic.php?t=225210)
Member josh.hibbler (http://www.thesamba.com/vw/forum/profile.php?mode=viewprofile&u=4498&sid=69bae7d15fc8d8e44d7d3fcf8566b7e9) from that forum mentioned:



... a "true" dual action sander has two functions, random orbital and grinder mode. you have to flip a ring on the shaft to switch from one to the other. a lot of da sanders are referred to as such, but not a true dual action sander. ...


While I am not sure if the points he said is right or wrong, this serves as a good reference in future.

To conclude, the terms Dual Action (DA), Orbital, Random Orbital (RO) are loosely used when it come to auto detailing because most likely we do not use the grinding function(?). They basically refer to the same type of machines that vibrates and rotate the pad to create a circular locus of pad that does not repeat itself.

nice to see that even Mark was a noob once...

[Kristopher1129]

I can't imagine spreading product with one, and polishing with the other. I personally think random orbitals are useless if you have a DA...any DA for that matter, ha.

Mike,

Sorry for digging up an old post but I think it would be nice to share some information with members of AutogeekOnline.




There's never anything wrong with digging up older posts because they often have information that's as relevant and accurate today as it was when it was written and posted. I often time reference posts I've made all the way back to 1994, long before the software you're reading this post on was invented or released.

One of my writing styles is to do what I call,

Write for the future...

That means, while most people reading a thread and the replies see the thread and the replies as it affects and relates to the OP that started the thread.

I know from experience that the thread will be around forever, (as long as Max continues to pay for the server the forum is hosted on), and this means people unrelated to the thread will be reading the information presented long into the future.

So my writing isn't just for the thread but for all the people that will read that thread into the future...


IF that makes sense....


That's why it's important to carefully pick and choose each word. That's another writing style called "Defensive Writing" and what that means if I make a post, I've already made sure if anyone wants to try to take it apart I can defend what I've written.

As a veteran of the Zaino vs NXT wars I've learned to choose and use single words very carefully.


:D

When I think of a random orbital...I think of the big clunky two handed machines. DA, I think of the more modern Griots, PC, Flex da, or Megs.

I know technically there's not much difference by definition between random orbital, or dual action. But to me, when someone says random orbital...I consider that an old term referring to the older style machines. Just my opinion. You don't hear anyone with a DA saying they have a random orbital....

[Mike Phillips]

I've witnessed people argue passionately over the terms Random Orbital and Dual Action over the years and I think it's much to do about nothing.

The big picture is this, get the "right" tool and use good technique and you'll get the results you want and dream about.

Millions of cars have been successfully buffed out with the person doing the work oblivious to the exact definition of Random Orbital or Dual Action and even more oblivious to the people arguing over their definitions.

It's all about KISS

KISS = Keep it Simple Simon


Helping a person to get a PC 7424XP, or a Griot's Garage 6" ROP or a Meguiar's G110v2 INSTEAD of something that looks like this is the big picture because it's the right tool for what they want to do.
