well i bought a used 05 gt with 12,000 miles on it and there are swirl marks all over it. i have used the mcguires 3 step on the hood, with one of those crappy $20 buffers you get at autozone, to see if the i could get some of the swirls out and after i applied the polish with the buffer i was expecting to see some results but you cant even tell i polished it, all the swirls are still there, what am i doin wrong?? should a buy a better polish?? am i using the wrong technique??
