For years I used a rotary then about a year ago I wanted a DA, I bought the Porter Cable XP, if did and an OK job if the car wasn't in too bad of shape, I found it took long to correct a car.
Then someone I knew who owns a red Camaro had tons of swirls but couldn't remove them even though he owned a Flex.
I showed up at his home with my Ultimate Compound , he had everything else needed.
In a matter of a half hour I had removed all of the swirls on the hood, he spend 20 hours but had no success , I forget what compound he had but it wasn't working plus he didn't know how to use the Flex, so I thought him even though I never used one before, very nice machine but the cost turned me away.
After that I starting reading up on the Griot's GG6, I took my time to figure out if I wanted the Flex or the GG6.
So I ordered the GG6, when in came in I looked at it, first thing I noticed was how well it was made.
I had my black RAV washed and clayed so I went straight to it.
The car had a lot of swirls so I put on a CG's orange hex pad and planned on using Meg's UC.
My test spot was on the hood, 2x2 foot area.
It didn't take long to realize that I bought a well made polisher, the power is twice as powerful than my PC, no matter how much pressure I put on it the pad continued to turn.
With only four passes the test spot was flawless, I was so excited.
I found it to work just as good as the Flex but easier to operate,it's well balanced too.
For half the price of the Flex I felt like I made the better deal of the two.
IMHO it's the best polisher for the money, it's all I'll ever need and have no plans to buy another more expensive polisher, I'm totally happy with my Groit's Polisher.
Plus you get a lifetime warranty.
Well that's my take on this unit.
