Just tried 6.5" pads with the Griot's Garage DA...

[WRAPT C5Z06]

It's always been pushed to use 5.5" pads with a traditional DA, which I do agree with, BUT, the power of the Griot's DA spins 6.5" x 1 1/4" pads with zero problems. I used speed 6 and even with heavy pressure, the pad did not stop rotating. I'm not sure the PCXP or G110v2 could handle 6.5" pads as well as the Griot's. :dblthumb2:

i am guessing you also used the 6" backing plate that came with the GG

Yep.

How about speed 5? Meguiar's have cautioned users about speed 6 in their G100, G110 and G110v2. I'd also feel the same way with the GG6 especially with the higher power of this tool. I don't want my BPs to overheat causing the velcro backing of my foam pads to melt.

I just actually stepped down from a 6.5" pad to a 5.5" pad. On my G110v2 the 6.5" pads rotate under pressure VERY well and it handles them just fine. That fact made me a little leery of the smaller 5.5" pad because I figure why go smaller if the larger size does fine?

I gave the 5.5" low-profile flat pads a try last weekend and my G110v2 had the famous power cord issue after about 20 minutes, so no direct comparison there. I did think that the 5.5" pads wanted to jump all over the place though and felt like the 6.5" pads were MUCH easier to control. After the G110v2 went bad I pulled out my old-school PC to finish the job and it was able to rotate the 5.5" pads under heavy pressure just fine, but only if the speed was cranked all the way up to 6. Anything less than that and the old unit was just too underpowered to apply pressure and still get pad rotation. 6.5" pads on the old PC don't work at all.

I'll need to try the 5.5" pads a little more when I get my replaced G110v2 to verify my initial impression, but if it holds up from my brief experience with them I probably will go back to the 6.5" pad size. The 5.5" size just felt too "manic" for me to be comfortable using them.

Just tried speed 5, and even with heavy pressure, the pad still rotated. Not quite as quickly as speed 6, but still very effective. Remember, this was with a 6.5" x 1 1/4"(thick) compounding pad, that's pretty impressive. A 5.5" pad on speed 5 will knock it out of the park with the GG, but a 6.5" pad still works very well. :dblthumb2:

Thanks Mark!!!

Have you tried using speed 6 throughout your detail session? Doesn't this heat up the backing plate like crazy? How are your foam pad's velcro?

About a month ago I tested all 3 of the DA Polishers we currently carry using 6.5" pads on a flat hood and as long as you use good technique, that is hold the pad flat to the surface, they will all rotate a 6.5" pad.

Heck Meguiar's did their testing with 7" pads and launched a new pad line for use with their DA Polisher and my experience with the company is that Meguiar's doesn't launch a product till they have all their ducks in a row. Sometime mistakes are made but they are very good at doing their field testing before launching any product. The 7" Softbuff pad is a dual purpose pad as it was also designed to be used with rotary buffers, so a compromise was made on size and thickness to try to provide a pad that caters to different markets.

Pad Saturation
That said, as a foam pad becomes wet or saturated with product, the combination of foam and liquid will act to absorb and dissipate the power coming out of any of the 3 DA Polishers but the Griot's will do better at maintaining pad rotation if all factors are kept the same.

Thin is in and smaller diameter pads
5.5" pads, and specifically thin 5.5" pads work better to take advantage of the tools unique drive mechanism but thousands if not hundreds of thousands of cars have been buffed since the PC was introduced from the wood sanding world to the paint polishing world since sometime in the early 1990's.


About a year and a half ago I posted that the Griot's DA Polisher kind of works like a safe version of a rotary buffer in that if it's able to maintain the rotating action to a pad under pressure... well that's basically what a rotary buffer is doing. To a lesser degree that could be said of any DA Polisher but there is a power difference between the 3 popular DA Polishers.

I only tried it at speed 6 for a short time. I can't comment on a full detailing session. :dblthumb2:

Thanks for the good information, Mike. :props:

Notice, I said I don't think the other two could handle 6.5"+ pads *as well* as the GG DA, not that they couldn't handle them at all. ;)

I actually sanded the hood down and then used the 6.5" pads to remove sanding marks and took iPhone videos of each pad at work but some other high priority projects took precedence.

Mark, do you have a way to create and post a video? If so, I'd like to see you replicate this test I did with my G110v2 using your GG6:

[ame=http://www.youtube.com/watch?v=QArfjNvSN2E]‪Meguiar's G110v2 Rotation Test‬‏ - YouTube[/video]

I'm sure you probably weigh a fair bit more than I do, but it would still be interesting to see how the polisher reacts under as much weight as you can put on it.

Charlie, I can try to post a similar video. What speed were you using and how much do you weigh?

If all 3 DA's are on a free spindle, unlike the Flex Da which is forced rotation..what makes the GG more powerful than the PC?Feed back please Is it strickly amps?

[C. Charles Hahn]

I was at somewhere between speed 4-4.5 in that clip. I weigh 145# (no joke -- like I said I'm sure you weigh more than I do!) but I'm guessing I probably had ~100# of downward force on the buffer.

Thanks!

This is the comparison I've been looking for. A comparison between 6-7 inch pads would be nice. Of course, it would be nice to see someone who has both of the DA's as they could better gauge the use of equal pressure on both.

I would think that if the Meguire's could keep up with the GG6, being less amps, and less wattage, it would tell us something about the cruise control feature on the Meguire's. It would also use less energy to run the machine.

I like the lifetime warranty on the GG6. I also like the wider "D" grip on the Meguire's, being able to easily change the brushes, and I also like the looks of the Meguire's better. Gosh I love choice's.
