I'm going to get one of these two DA's, and would like to know everyone's thoughts on these.

I've always done things by hand but now that I bought a new car I want to up the game a bit with an electric polisher. I don't know anything about the ones you have in mind since this is my first polisher but I bought a Griot 6". It was either that or what for the new one from HD. Have you considered either or both of those as well?
 
I'm only going from my limited experience, I'd lean towards the G110v2. I have a v1 and it's served me pretty well besides having to jerry rig the cord (not bad after 3 years of decent abuse). With the v2, it has a "cruise control" that when you begin to put pressure against the panel you're working on, a clutch is engage which allows the pad to continue to to spin at a decent rate as opposed to the v1 where it'll slow down significantly and most times even stop spinning (I hope I'm explaining this right!) Also another feature allows you to change out the brushes more easily as opposed to opening up the back of the polisher to access them. Also I do believe it has a bit more power compared to the v1 and PC.

I'm also shopping around and I'm looking between the v2 and Griots 6. However I'm holding out to see what the 3D polisher brings to the table. The v2 also had cord issues but I heard it's been resolved?? The Griots 6 has more power then the v2, is cheaper, and comes with a lifetime warranty.....just something to keep in mind when choosing.

Hope this helps ya and I'm sure someone will chime in with a lot more exp then me!

I'd suggest that you wait just a bit more and see how the 3D PC compares.



I agree with BigAl3 list.

I hope it comes out soon. I'm trying to sell my mini-laptop to buy equipment, and want to get started asap.
 
No machine is perfect, but other than durability of the machine... procedure, procedure, procedure will make a MUCH bigger difference than the brand of machine.



I favor the Meguiar's G110v2, but I also sell them! Please take this into account when reading my opinions.



The Meguiar's G110v2 has had its share of hiccups since its introduction several years ago. Mainly, there was an electrical cord issue with some machines, and a very short stint which saw the speed switch going out. Those problems have been resolved.



The G110v2 is NOT subpar to the Griot's, the DAS-6 Pro, or the 7424XP. In fact, I've seen OPM speeds verified via tachometer that prove its ability to outgun the aforementioned machines on the top-end AND deliver more backing plate rotation. That being said... there seems to be a HUGE variation in speeds with all of these machines; a machine built with an acceptance of plus or minus 10% in regards to its claimed speed rating means that a machine rated to deliver a maximum of 6,000 RPM may actually deliver 5,400-6,600 RPM. In most cases, the speed is on the low side. When a machine seems to be super-powerful in my hands, more than likely it is nearly delivering or actually delivering its rated speed. Sad but true, from what I've been able to verify.



Jason Rose has seen a competitor's machine deliver 13,000 RPM no-load speed, only to slow to a death crawl of 3,600 RPM under load (polishing paint). This way likely an anomaly, but it was verified, and the machine continued to chug along.



The weight and rigidity of a machine's backing plate, the "tightness" of its shaft & spindle bearings (which likely also have an acceptable friction variance) can also affect ramp up speed, ability to maintain a constant speed, and overall speed of the machine.



While I used to look for maximum speed and rotation (my G110 still runs HARD, and it's "diminutive" 4.2 amp motor can deliver 6,500 RPM and 10-12 turns of its backing plate outfitted with a 5" DA microfiber disc), nowadays, in terms of performance, I am mostly concerned with:



• Ample backing plate rotation (more is generally better)

• Low-speed capability (for final finesse-polishing)

• An accurate and progressive speed dial



The current crop of compounds and polishes perform remarkably well using low to mid speed settings, and future formulations look to do the same. This is great news because paint seems to stay cooler when polished using lower speeds (a topic for another day!), liquids last longer, machines run quieter, and user comfort is something we can actually start to expect when using a random orbital!



Compounds are loaded with ultra-fine but grippy abrasive these days, and microfiber discs place a tremendous amount of surface area in contact with the polishing surface. Add the two together, and you can almost expect to see random rotation of the backing plate slow due to friction. The G110v2's Cruise Control feature can really be an asset when polishing using lower speeds (where not a lot of centripetal force is being generated, which is what makes the backing plate rotate).



As to a lifetime warranty... I am always for that, but not if the product I'm buying is constantly breaking. If I'm required to have a backup on hand because it's common knowledge that there are durability issues with the product, I'm not too keen on buying that product.
 
I have only used the PC and have had two of them and I will def say I won't be getting a third. I guess $120 at the local tool store is a pretty good price but when they only last a year, I'd rather spend a bit more and get a more durable machine. Speed selector switch went on the first one and my other one just froze up and started smoking. Using an older model now as a backup until the 3D comes out.
 
If I get the money before the 3D comes out, then I'm probably going to buy Meg's g110. I'm sure they are all capable machines, but I like what I hear about it, and I like the handle placement. It may have been silly of me to start a thread about this, knowing I would get different opinions.



But as soon as I get ready to order, I will have more questions about what other products/accessories I should buy. Thanks for the insight guys, as usual you are the best.

Because of this well written post I just ordered a G110v2. Thanks, Kevin.
 
to the OP - if you order the GG6 direct, you can try it for 180 days (6 months) and if you aren't happy with it, you can return it for credit or full refund. if you can wait.. see what the new HD DA brings to the table, and go from there. i wouldn't hesitate to go with the G110v2 as well, but the PCXP would be my last choice...

You are most welcome... I'll look for your order on the Buff Daddy site..! Ayyyy, just kidding. :)

ADS @ $142 or Amazon @ $149. I sell it at $184, or $154 in a kit. Tough being the little guy, but when I get an order... it's a happy day!
 
Kevin Brown- Thanks from me too! I'd dismissed the G110v2 in large part out of my, uhm....general disinclination to patronize Meguiar's any more than necessary. Sounds like I might oughta rethink that...
