Sounds like you needed to either move up to SSR3 or go with a more aggressive pad...
according to these descriptions:
# Yellow Medium Cut Pad (E-621Z). This pad is useful for light oxidation and moderate to severe swirls and imperfections. This pad will yield amazing results on older vehicles, and should be used on vehicles with moderate swirls and imperfections. Add a compound or pre-wax cleaner for a flawless finish on base coats. 50 pores per inch (ppi)
# Green Light Cut Pad (E-622Z). This pad is highly versatile, as it can be used on cars with light to moderate swirls and imperfections. We recommend you begin with this pad if you are unsure how deep swirls are, moving up to a Yellow Medium Cut Pad if necessary. Safe on clear coats. 60 pores per inch (ppi)
you needed the yellow pad not the green one as the green is for light to moderate problems..if you needed that strong of a product with a rotary , you probably would have needed to use a cutting pad first.
