THe Zaino users I know go for Menzerna Intensive Polish I and II or Optimum Hyper Compound when using the orbital. Maybe they've started using this product but I haven't heard of this yet .
I use the Poorboys SSR 1-2.5 and its really for maintenance, you really have to put in some sweat to get the results of the Menzerna which is less maintenance and more corrective. The pad you are using also speeds things along. You may want a to go for a cutting pad rather than a polishing pad. Anthony Orosco at Optimum will talk your ear off on this subject he knows all Porsche stage paints.
But if you have light swirling I'm sure the Zaino will do the job. Hope it works, that's a time consuming job I don't like to do more than oce. May be a good idea to buy some cheap lamps at Lowe's and work in the dark.
