Technically speaking, providing you have the correct pad for the job, any product that can be used be hand, can also be used by machine, although there are some that I wouldn't recommend it.

Of those you listed there, both the clearkotes work reasonably well by machine (is it rotary or random orbit/dual action Silverline you have, Brian, btw?)

If you have Poorboys products, then the SSR2 is a good product to begin with and will remove medium to mild swirlmarks, light RDSs (Random Deep Scratches) etc. SSR2.5 for heavier correction work and you will probably need the SSR1 to refine and 'jewel' the finish after the SSR2.5, although the SSR2 (depending on the type of paint and the pad being used), can be finished down to an LSP level on its own without needing to be followed with a finishing product like the SSR2 or Menzerna PO85 Final finsh for example.

If you can give a bit more info on what pads you'll be using with it and exactly what you're trying to achieve, then I could assist further with more specific info.

Cheers
