The Megs one is a dual-action polisher which means it does not rotate purely about the central axis, but instead has a little throw in its action. The effect of this is that is does not generate much heat while working the polishes when removing the swirls. Therefore it is okay to be used by most car owners. It's the type of machine that 99% of people start out with to learn the basics of machine polishing and defect removal.
So, don't worry. And if you work the polishes slowly by moving the machine at a rate of about 3cm per second on the VAG paint you will create a big improvement in the finish.
You'll need a 3.5 inch and 5 inch backing plate for 4 inch and 6-6.5inch pads. You will need both polishing and finishing pads and maybe even a cutting pad, depending on the defects. The 4 inch spot pads are ideal for tricky areas like bumpers and door sills etc. Polished Bliss sell both sizes of pad, including the plates.
For polishes, you'll want Menzerna 3.02 Intensive polish and 106FA Final Finish and 85RD Final Finish. If you are just doing your own car then to keep costs down I'd recommend getting 250ml bottles instead of the litre ones. These will do about 4 cars.
The 3.02 will probably turn out to be your best bet on the VAG paint with the DA polisher, work it nice and slow. You will then poss finish off with 85RD on a finishing pad, although 3.02 does give a nice glossy finish if worked long enough. When I done my own car about 7 months ago, I used 3.02 on a polishing pad, then 106FA on a polishing pad also.
If you have the time then you can give the car another going over with 106 FA if you are careful with your wash routine over the year.
Check out the polished bliss guides first if you have not already done so and check out the machine polishing section on detailingworld too. Make sure you know a little bit about the process of polishing first.
It would be useful getting a local detailer to do paint measurements for you anyway so that you know the state of the levels. It would give you reassurance. Using the polishing pad and menz 3.02, working slowly should remove about 2 microns.
Hope this helps,
