Either one of those methods should work, chances are very good the TSR on a DA with a Polishing pad will remove any swirls left by the rotary step regardless of whether anyone could see any without first chemically stripping the paint.
The Menz SF4500 with a rotary buffer is pretty light but again, any swirls left by the Rotary Buffer and SI 1500 with a foam cutting pad would be shallow too...
If it were me, I would opt for the TSR with the DA and a foam polishing pad.
Is this fresh paint you're working on or factory paint?

Re: Dampsanding Tools, Tips and Techniques by Mike Phillips
Mike thanks for the feedback and it really is because of your coverage of this subject that I finally made the jump and decided I could/should do this.
My paint is about 3 yrs old and is a very soft clear on a show car. It atill sands like fresh paint in my opinion. My only concern at this point is that I should have bought some 1500 discs because the 3000 didn't correct everything. So Ive had to spot wet sand with 1500 and then dampsand 3000 to get what I want. That still may prove a safer approach, definitely cheaper. But I wanted to sneak up on it until I got a feel for how much material I was removing with the dampsander. In the end, although slurry was thick, the 3000 was pretty tame.

Yes, the foam backed #3000 is very non-aggressive and even more so with an interface pad.
If a person is new to wetsanding by hand or by machine it doesn't hurt to start out using the finer grits to get a feel for the process and as your comfort level increases to drop down in aggressiveness.
The biggest and most important factor when it comes to safely wetsanding is film-build or paint thickness. I'm in the camp that believes more paint is better. This reminds me I have an article on this topic to finish.

Are the blue towels to protect the windshield available on AG? I see they have the logo but can't find them.

If you're interested in wetsanding by machine give this thread a read-through...
It will be a good primer for my next article on this topic.

You want to see the backing pad/sanding disc rotating no matter what, so adjust your speed accordingly but I would try the 4-5 setting. The 6 setting, at least for me is too fast.
Also, I would highly recommend using the foam interface between the backing plate and your sanding disc, you'll experience a lot smoother sanding action.
What are you working on?

Thanks for the reply Mike. Ill try with the trizact 3M sanding discs as those are the only available here in Guatemala. and i 'll have to wait a bit to save more $ for my next order. I have a trunk and a hood from a toyota to practice, as the paint is really sof and thin i think it will be a good practice.
My current detailing project is a 2004 Seat Leon. it is yellow and it has been repainted with PPG Global system.
The roof will be a big challange it has just 2 coats of clear, and tons of orange peel and dust, it was repainted in a hurry as was not planned to be painted i dont care if i broke through the clear as it still will be refinish with other color. so i think it will be a good experience, still i'll be really careful with it.
i'm traveling to taiwan, so i'll post pictures the next month hopefully.
I was afraid that the GG6 was to aggressive to damp sand my car! thanks for the clarification!
