Glasur lasts longer than BOS i would probably choose that, i doubt ill be using BOS on my own car this summer even, ill let you have a crack with the rotary if you want, they are dangerous, but they are easy to handle with a polishing pad and polish, its compunding that makes it all dangerous. Its plastic pannels you want to watch out for.
ABOO, if you can do damage with a DA ill be amazed. Ive ragged the s**t out of cars using the DA and it just doesnt do any damage. Rotary however takes all of 3 seconds lol.
Oh, i have the S1m 180, similar machine.
