A surface polishing system leaving a surface free from streaks and swirls after the application of a polishing composition into a painted metallic surface includes a polish applicator having a vibrating motion attached to a pad assembly covered with a supersoft 100% polyester material and a polishing composition of 15-30% by weight of high purity aluminum oxide having a particle size of no greater than 0.3 micron or 300 nanometer and 3-20% by weight of calcined alumina comprising at least 70%α-aluminum oxide (Al2O3) with a low calcination degree and a primary crystal size of less than 1 micron, the combined high purity aluminum oxide and calcined alumina having a total concentration of 30-40% by weight of the polishing composition. |
