I chose the 15. I have a Flex and a UDM 1.0. For what I do the Flex is fine for correction but I use the DA more for AIO/paint cleaning and LSP application.
I had planned to replace the UDM already with the GG but the reviews were not much different than the prior models so decided why wait. I have worked planned soon as the weather warms up so decided to be ready.
Al, do yourself a favor and try the Rupes 15 at correction, too. It may not be quite as awesome as the 21, but I would predict you will really like it there, too.
The way I understand it is the 15 vs. the 21 is the orbital rotation. Is the 15 smaller in overall size than the 21?
My understanding the only difference is the orbit and backing plate but Mike can confirm since he owns both. The 21 comes with 6 -in and 15 comes with 5 but may depend on who sells it. The body is the same.
Did some light paint correction on this 2013 Ford Focus. I was amazed at how the paint was already covered in micro scratches from inproper washing. Didnt get much pics as I didnt have a outside light and I was working against the sun. I did manage to get a few though. I ended up having to use a pink LC pad and some PoorBoys world SSR1 to remove most of the scratches. Then followed that with a white LC pad and PoorBoys world polish, followed by a black LC pad and Black Hole glaze. Of course it got topped with BFMS.
It is sunny and 45 today. It was warm in the sun but still did some inside work. I got the electric heater going in the garage. It started at 48 and got it 60.
MKZ: I cleaned the glass inside with Mothers Glass Cleaner and used Sprayway on the exterior.
Dakota: I vacuumed the interior with the Metro and cleaned the carpet with Chemical Guys NONSENSE cleaner. The jury is still out on NONSENSE even at full strength.
I also applied Mothers Protectant on the interior then I removed water spots on the exterior with a Rupes 15 and a 5.5-in Lake Country Tangerine pad and Mothers Water Spot Remover. I cleaned the glass inside and out with Meguiars Glass Cleaner.
My comments:
1. The rear end is just as long as the Flex so a consideration with hand/body position compared to the PC. The line cord was on the stiff side. For people with short arms, this is a consideration.
2. Very refined whirring sound at speed. Flex has a more gear grinding sound. The vibration overall is comparable - both nice.
3. The finger switch behaves a little different than the Flex. It is just on or off compared to the progressive action by the Flex. It will lock.
4. The Rupes has a soft start and goes slightly over speed before stabilizing. The speed control is very easy to use - enough detent to prevent accidental movement.
5. The overhang at the front seemed a little smaller than the Flex.
6. Plenty of power.
7. The backing plate keeps a tenacious grip on pads.
