GG6 vs Duetto

After reading these responses I may even consider the PC 7424XP which seems like an overlooked sleeper in all the commotion over the latest and greatest products. Can you change backing plates on the PC without worrying about the counter weight? What pads for the PC? Terry
 
It would be interesting if AG would publish the sales figures for the various polishers to see which ones are really the most popular.
 
GG6 is value for money,bang for the buck.
Rupes Duetto if money is not an option.

Yes, no problem. Although perhaps not designed for the smaller Backing Plates, most users usually have a variety of sizes as this then eases and enhances use in smaller areas.

Thus there's no real issues due to the counterweight size and weight not being thought to be optimal and then changed. Usually one does not use such smaller Plates and Pads to do an entire vehicle, just in harder-smaller areas, such as A or B Pillars, Bumpers, Headlights, tail lights, or where trim moldings might hinder the use of the larger backing plate-pads.

Sizes that would be commonly selected would be a 3.5" Backing Plate (for 4" Pads) and 2-7/8" Plate (Lake Country commonly calls this a 3" Plate, and can be used with 3" Diameter Pads)

I myself have a large selection of the various Lake Country Flat Pads in 5.5" Size. They are high quality, durable, have beveled edges.

The PC is supplied 6.5" White Pad with permanently attached cheap plastic Backing Plate. Far from optimal for polishing, and no ability to swap pads, but with the correct size MF Slip on Bonnets, this combo would make a nice 'Waxing" combo for larger vehicles such as trailers, RVs, Motor Homes, Boats, large trucks etc.

Basically, the rule of thumb with any pad choice for any of the DA Machines, is using Pads which have the correct amount of overhang. This then helps insure that you won't be running the backing plate edges into the paint.

The "thin is in" adage is both advantageous for either the PC, or GG Machines. Less mass, and less "give" hold advantage for better consistent Plate-Pad rotation, that these free spinning DA Machines aren't then just wobbling-vibrating due to lack of rotation.

Such was generally the "flaw" with older Orbital "wax" Polishers from the likes of Waxcoa-Craftsman. Fine for waxing, but little in the way of being a tool that could be used for paint correction.

Hope this helps.
 
Although I'm happy with my PC7424XP Machine, and that the only way I'll be replacing it, is if it should break.

The one minor dislike of the PC, and not sure why they did this, is that there is no "Detent" to choose a speed setting such as 5.5. Meaning there is only speed 5, or speed 6 on this machine. And I, and probably some others would agree that such a speed actually may have been the very best in common instances for correction.

That there can be a slight propensity of rotation stall at speed 5, dependent largely on pad selection, over-loaded saturation of polishes in the pad, and lack of properly maintaining the correct flatness of the pad to the paint surface.

And speed 6 (highest setting) seems a little bit too much, the machine is considerably louder as well.

When I bought my PC7424XP, the Rupes models, or the Flex Free Spinning DA were not yet in production.

There's certainly more to choose from at present day. That yes, if I was buying today, I myself would definitely be investigating-researching machines from either Flex or Rupes.

The GG or the PC can be likened to the Chevy or Fords, whereas the Rupes-Flex Models could be considered the BMW-Mercedes Benz, better quality machines, and of course more expensive.

Totally agree.

I have a very specific technique with the PC, and a certain set of pads, but the more universal approach of mine would be to pair the PC with Lake Country Hydrotech pads. I also like to keep a set of fiber pads with me too.

I liked the LC UltraFiber pads, but they're coming out with an updated version soon. Also, the Buff and Shine microfiber pads are INCREDIBLE! You'd be surprised what can be done with fiber pads, and a cutting compound - even on a PC.

1500 grit scratches are no joke. The owner of this car is a childhood friend of mine. He had me come out to polish one of his work trucks, and cut and polish his Chevelle.

Before I got done with the truck, he hit the car with 1500. All I brought with me was the 1st gen Porter Cable - the "weakest" machine known to man. He had a rotary, but it's beginning it's downward spiral to the landfill..

I used a combination of green hex logic pads, and green LC prototype pads along with Meguiar's M100 to get this result. The trick is to balance the pressure. I can tell you that it's nowhere near 15lbs. That works for others - guys who know more, and are way more experienced, but this technique works for me. The pad will fly on this thing, something the fixed rotation of the Flex 3401 won't do. The Flex can handle pressure which isn't part of my technique.

GG6, PC, you're in good hands. The reasons I stay with the PC:
1. Compact spindle housing. - Makes it easier to see work area when swapping out to smaller backing plates.
2. Manufactured for use world wide, not confined to the smaller detailing industry. Their tools can be easily found at certain big box retailers.
3. Unbeatable reputation for quality and durability. Considering these machines are widely used in other industries - often without incident assures me that I'm getting a reliable, high quality tool.
4. Double insulated. If working in a wetter environment, it further protects the operator from shock.

I've had my 7424xp for six years now, and it's never let me down. In fact, it's saved my hide when other tools weren't getting me the results I wanted. These days I usually opt for the 1st gen tool I found used on ebay. I got two of them brand new, and like that it's smaller and lighter.
 
Anyone have any comments on the amount of vibration with the GG6 & PCXP??

I could be wrong, and somebody please correct me if I'm wrong.

I've been a member here since Oct 2012, And I believe the latest GG-6" model is referred to as the Generation 3 model. Meaning there was some ergonomic improvements and as well I believe a more powerful Motor used in this latest design.

But while I don't think I've read many numerous user reports of a seeming high number of vibration dislikes with the GG-6", I believe I have read a few. And gather that it may be a little more than the PC Machine, which I cannot recall reading such about unless the Machine was somehow defective.

While I've seemed to note less complaints of vibration with the Porter Cable 7424XP, I can tell you from personal use-experience, that yes, it vibrates, and is a bit noisy as well. Loud enough that your neighbors will know you are doing "something" with some sort of machinery.

While I've never used a Rupes, it appears that from other's accounts in evaluation of their machines, usually one notable comment they seem to immediately notice, is that they are a good deal smoother in operation than the PC or GG DA's.

There's surely a good number of folks here who have had numerous brand DAs, and can hopefully comment, and give you better personal accounts of such qualities
 
On a website such as youtube, you could probably find any of the modern machines made today and see them in actual use. This might then give you a better understanding of the various machines, their ergonomic features, and also get an idea of sound-etc.

Would not surprise me one bit, that you will find our own forum expert, Mike Phillips at the helm in many of these tutorial vids, using any one of these machines from the likes of Flex, Rupes, Porter Cable, Mequiars, Griots Garage, etc.

Again hope such helps you choose and decide.
 
The GG6 is a little beast, the vibrations not bad at all and it has the torque to power through all curves.

2nd and 3rd generation have the same power.

If you keep the 6" pads off of them, the vibrations aren't bad at all. Very rarely do I experience vibrations with the 7424/7424xp.
 
I am a 72 year old man who recently has become obsessed with getting a car polisher. I am in pretty good shape.

Run 4 miles 3x a week and take of a home on 5 acres of land in Florida.

I don't really need a polisher, but I want one. It all started with getting a new car and polishing it with KAOI followed by Collinite 476s,

So I began perusing car detailing forums and here I am.


Because you're in Florida, here's an idea, come down to my FREE class this Wednesday, (tomorrow) and you can use a few of the tools you've referenced before you buy.


Wednesday Night Project - June 27th - 5:00pm to 9:00pm



I don't have time to do these mid-week class as much as I use to as I'm a tick busy doing our pay-for classes, like the New Jersey Roadshow Class I just returned from.


Up to you...


:)
 
It’s been 2yrs. since TJinFL asked this question.. Lets hope he pulled the trigger on a polisher by now.
