which DA

I am looking for one polisher. The choice is between a PC or the Griots, since no one seems to ever recomend the flex. Havent really found a answer to which one is better or prefered. I used to detail in body shops with rotary but that was more than a decade ago. I will be using Adams products if that changes which one to pick. Thanks Everyone

I personally prefer the Griots. The PC seems to bog down pretty easily. But hey, don't listen to me because I'm sure I'll get bashed by a lot of people that haven't tried both. The Griot's also comes with a lifetime warranty no questions asked.

Both are great machines, but I like the Griot's Garage 6" Random Orbital Polisher that also comes with a lifetime warranty from Griot's.

It comes with a backing plate, have you ever use a DA before and do you have pads/polishes to use?

I'm also a rotary guy for many years and found the DA machine with the right pads and chemicals do awesome work. My go to pads are the Lake Country Hydro-Tech 6.5 Inch Foam Pads using the M105 and M205 products.

Someone gave you bad advice not to get the flex, its by far the better polisher out of those three. In fact, its in a different catagory and therefore, a higher price point. If you want to spend two or three times the time correcting your paint with a PC or Griots, feel free. If you can afford it, get both of them and use the PC for the 4" focus pads only. I wish I would have bought the flex as my first polisher and skipped the "ole trusty PC" stage of detailing...lol

If you're going to use foam pads only, then yes get the flex. If you're gonna use MF pads which I highly suggest, then get the griots as the flex doesn't work well with the MF pads.

No problem. I have both and love them both, but I honestly reach for my griots more than I do the flex. I just read that you're going with Adams. I would definitely get the flex then. It will probably feel more right in your hands since you're use to a rotary. I just wouldn't limit myself to Adams. Not to say they aren't good, but I really like the new Meg's MF system, it cuts polishing time down a lot.

Choosing the correct machine can be tricky and confusing. After all they are significant investment and there is a lot of information, sometimes conflicting information about the machine polisher's you can purchase for your car.

All machine polishers work by creating friction on the paint's surface. This friction caused by the movement the machine polisher creates as it moves a polishing pad across the surface. It should be noted that since all machine polishers create friction and the process of polishing paint means that you are removing paint, there is always some risk involved.

Types of Polishers:
  • Dual Action Polishers: Dual Action Polisher, or DA Polishers, work by moving the pad in two patterns at the same time. They combine an oscillating movement (tiny orbital movement) with a spinning movement. Depending on the type of machine, the spinning action can be free wheeling (Random Orbital ) or direct (Forced Rotation).
  • Rotary Polishers: Rotary Polishers, which are also referred to as Variable Speed, High Speed, and/or Circular polishers work by moving the pad in a spinning motion. These machines generally create much higher friction due to the rapid rate at which they move the pad.


DA Polisher Types: - Since this article focuses on choosing the correct Random Orbital Style Polisher, we will look at the two types of DA Polisher Types: Random Orbital and Forced Rotation

Random Orbital DA Polishers: Random Orbital DA Polishers have a free-spinning or free-wheeling pad. There is no direct drive between the pad spinning and the motor. Random Orbital DA Polishers instead drive the pad in a tiny orbital movement that very much mimics the movement of your hand if you where applying wax in the Mr. Myagi "wax on/wax off" motion, only much smaller circles and a much higher rate of speed.

A free-spinning bearing connects the backing plate (pad mount) to the machine. Centrifugal force, created by the tiny orbital motion, allows the pad to spin. Since there is no direct link between the machine and the rotation of the pad, applying too much pressure will cause the pad to stop rotating. This can prevent over heating the paint as well as prevent to much paint removal.

On the surface, Random Orbital DA Polishers are the safest and easiest to control for new users. Random Orbital Polishers have another unique advantage. Because there is no direct link between the rotation and orbital movements, it allows the pad's to create an infinitely variable (hence Random) pattern of movement across the paint. Manipulation of this pattern, by experienced users, can dramatically increase the cutting power or finishing ability.

Random Orbital Polishers-

Porter Cable 7424 XP- Porter Cable, with the original 7424, is the company that introduced DA polishing to enthusiasts. The "XP" has more power, more speed, and less vibrations. While some would say it "only" features a 1-year warrenty, many would argue that they never need one to begin with.

Griot's Garage 6 Inch DA- The Griot's Garage is a power house with a life-time warrenty. It features a power 850 watt motor that may resist bogging more than the other models.


Meguiar's G110v2- The Meguiar's G110v2 features a soft start feature, rubberized soft-touch body, and ultra smooth performance. It also has the same high speed as the other polishers and a powerful motor. It is a little more polished then the other machines, but just as capable. It also features an extremely accurate speed dial.



Forced Rotation DA Polishers: Forced Rotation DA Polishers get their namesake because the directly drive both the orbital motion and the rotational movement of the pad. The pattern the pad creates as it moves across the paint's surface is controlled and never changes; the only variable is the rate (speed) of the movement. These machines are very much a blend between Random Orbital DA Polishers and direct-drive Rotary Polishers.

Instead of a free-spinning bearing assembly, Forced Rotation DA Polishers use some type of gearing system to tie both movements together. This adds to the complexity of the machine, but also increases the available polishing power, particularly when pressure is applied. With a Random Orbital DA Polisher the pad may stop spinning under pressure. With the Forced Rotation DA Polisher it will continue to spin (and orbit) increasing the potential for polishing power.

Since the pattern of movement of the pad is fixed (the pad will orbit a fixed number of times per rotation) the only variable the operator controls is the rate (speed) of movement and the pressure. This actually shortens the learning curve of the machine and allows almost new users to achieve maximum results with little learn time.

The flip-side is because the motion is directly driven there is more heat transfer to the paint. Forced Rotation DA Polishers will also drive or stear more across the paint as they work. You do trade some safety for the increase in polishing power, although it still remains an extremely safe way to polish paint.

Forced Rotation DA Polishers-

Makita BO6040 Polisher- The Makita "Two-Mode' is unique in that it features both a Random Orbital mode and a Forced Rotation mode. Simply turn a dial to switch between the different functions. Unlike the other polishers in this article, it features a smaller, 3/16th in stroke (the distance of the orbit) which makes it great for machine sanding in Random Orbital Mode.


FLEX 3401 VRG Dual Action Polisher- The FLEX 3401 is one of the most popular polishers on the market and for good reason. It gives polishers the ability to remove serious paint defects quickly on the first use. A variable speed dial and variable speed trigger allows the user to find the right speed for the application and the rugged design never seems to dissappoint.


Picking the right polisher:

Before deciding on the exact model it is good to first evaluate your needs and the style of Dual Action Polisher will fit you.

Random Orbital Polishers (Porter Cable, Griot's, Meguiar's) used to be considered under-powered beginner's tools. Now with the advent of modern pad systems (low profile foam pads and microfiber discs) and abrasives this is no longer the case. In fact there has been a resurgence in Random Orbital Polisher use with advanced and experienced users. Learning how to master the Random Orbital DA Polisher takes a lot of time, but for the few that have, you will rarely see them use another machine.

Forced Rotation Polishers combine many aspects from Random Orbital DA Polishers and Rotary Polishers. The result is a polisher that has near the cutting power of a rotary while being nearly as safe as a Random Orbital DA. For many enthusiasts this is the style of choice. With minimal experience they can generate incredible results, quickly.

Regardless of the sytle of DA Polisher you choose, Autopia-CarCare has the support team and the tools (pads/polishes/towels/misc items) to make sure you are on your way to high level polishing.
