Just note if you are using the polishes with a rotary vs a DA - the rotary will be more aggresive and therefore requires a bit more caution.
Obviously it wont strip paint to bare metal if you so much as blink (like some peeps would have you believe), but if you are using a rotary, step up through polishes and pads with a bit more thought than a DA.
I'd add though my Golf has very hard paint - you'd be a complete chopper to burn through it with anything so it's a balance of time and effort
