No sense "Busting Swirls" with that pad when you're only using Optimum Polish (OP). OP is a finishing polish, designed to make a "Swirl Busted" finish look deep and wet.
SwirlBusting requires a SwirlBuster type pad (Yellow, Orange), and be used with either Optimum Compound (OC), or Optimum Hyper Compound (OHC).
Then OC or OHC with OP on a white polishing pad, and you'll be amazed with the results :getdown
