2006 it's hard to say unless I see the car. Is the edge green pad a light polishing?
I would try maybe #80 or SSR 2.0
If the car is pretty bad #83 or SSR 2.5 (I follow this up 99% of the time.)
I just did a dark blue 01 or 02 VW jetta with SSR 2.5 on rotary and SSR 1 on PC.
I would say I removed about 90% of the swirls. I was pressed on time or I would have done an area or two twice. but the car looks great, I'll be waxing or sealing it this weekend, may be I'll hit those few trouble spots again, before protecting.
