I'm seriously considering the new MT300 and was wanting some opinions on it and the new Meguiars foam pads. I was going to pick up the Flex and still may in the future but for now I think this might work well for me starting out.
SO I tried out the Meguiars system at detail fest. The MT300 with the corresponding backing plates and foam discs are amazingly smooth and it is effortless to use.
I have a FLEX right now with the 5" LC hybrids with the LC interchangeable backing plate system per Mike's book. I have to say it is a freaking beast at doing its job. The one problem I have with it that it DOES pull. It can be controlled but it is a constant effort on cars with a lot of divides or body lines in their metal. I have years of experience using a rotary so I know what to expect.
I am looking at going to another system because recently, I had my first full 8 hour session with the FLEX and it's a mixed bag. On horizontal surfaces, great but I do not like it on vertical. If you don't have a good angle on it, to me, it wasn't an enjoyable experience.
Going back if I were going to buy another system, it'd be the RUPES or MT300 systems. For the type of jobs I do, I'd rather have a little more time invested without the physical toll the FLEX takes to operate.
And again.. I had no buffer hop, no weird movements. It was very similar to my rotary but just.. more grab it seemed. To me it's more of a system of putting pressure down and really feeling the pannel and how it's shaped and directing it.
My .02$ is that I'd like the FLEX for DA compounding but for a majority of the compounding and polishing, I'd greatly prefer my rotary or a DA such as the RUPES or MT300.
