Does the low end speed of a DA Polisher make a difference in the final appearance of the car?

The 4 DAs I am considering are the Meguiars G110v2, Porter 7424xp, Girots 6 inch, and non-AG available Harbor Freight 6 inch.

Both the Megs and HF show a low speed setting of 1800rpm, while the Porter and Girots show 2500rpm. The HF has a max of 6400rpm, which Megs, Porter, and Girots show 6800rpm max.

One other option I'm considering is the Megs DA Power system, but my current drill is a little too slow (about 1300rpm max).

Before I invest in a DA, I want to make sure I'm getting the right one for me.

Thanks!

The answer is "no".

For anything you'll ever do with an entry level DA polisher like these I can't think of a single thing you would use them for using the lowest speed setting except maybe the Griot's Garage version of the PC and this would be for machine applying a wax.

For correction and polishing work on paint, for machine scrubbing tires clean, for machine scrubbing molded-in non-skid surfaces on a boat, for machine sanding, etc. you'll be using the medium to high speeds.


Hope that helps...

Thank you very much Mike!

It definitely does help. Now I need to take some time, build myself a good comparison chart, and try and determine which one is the most idiot-proof. If there's a way to foul something up, I'll figure it out.

I'm kind of leaning towards the Meguiars at the moment. The "Cruise Control" feature on it (where it keeps rotating under pressure instead of slowing/stopping) seems unique and gives it an early edge.

With the Griots you really don't need cruise control since it has enough power (while still being safe) to keep the pad rotating with a good amount of pressure. On top of that it has a lifetime warranty and Griots has great customer service.

If you're sold on Megs--have you looked at the new MT300 polisher??
 
I think the MT 300 is probably a bit more machine than I need at this point. It does look nice though. It'll probably come down to Griots vs. Megs. The HF looks like a coin flip - you might get a good one, or you might not. The PC, while a big name in DA, isn't drawing me in.

GG6 :dblthumb2: I had a PC for a while, now I'm fortunate enough to be able to have a few Rupes machines, but I bought a GG6 any way and compared to the PC I'm going to have to go with all the other hundreds of posts on the forum GG6 :dblthumb2:
 
The speed the machine is spec'ed at is completely useless info IMHO on a free spinning DA. Type of pad, size of pad, product, your extension cord, and an infinite other amount of variables will affect how fast the machine actually spins the pad on the paint.

These "specs" are for the unit free spinning. Once you put it on the paint with yr setup, that don't mean much. What does help is torque/power.

The Griots 6" beats them all.

First of all....:welcome:to AGO Ryche! :)

As Mike said, the low speed isn't what you'll be using. You'll be using 4.5 to 5.5 most all the time.

I'd say get the GG6 and don't look back. With an extra set of brushes (for the motor) and a lifetime warranty it's a no brainer. Do make sure you get the 5" backing plate though!

Also, get AT LEAST a dozen pads!!!!!!!!!!!!!!!!!!!!!!!!!!!
I'd say 4 orange, 4 white, 2 blue, 2 black and that's a bare minimum. The trick is your orange and ESPECIALLY the white will be used much more than any other pads you have.

FWIW, you can (if you know the right people) find a 30% off coupon at Advance Auto Parts and order the GG6 from them. ;) For some reason they won't take that off the small unit but they will come off of on the big one. :dunno:

Another pad kit worth looking into would be the Meguiar's DAMF Kit. That's the "DA Microfiber Correction Kit". Autogeek has the kit with a 5" backing plate that's designed with the Meguiar's Velcro to work with their pads (and not overheat), plus D300, D301, 2-cutting pads, 2-finishing pads, and even a Meguiar's apron. ;)
