I'm new to using a pc and yesterday I was polishing a infiniti g35 (black). I started out with lake county orange pad with m105, and it was doing a decent job of removing swirls but I kept leaving buffer trails. I then moved to m205 with white pad and then also tried m205 with black pad but the trails were still there. Do you think its from me not making enough passes or what? The m105 seemed like it was drying up real quick and didn't have much working time, so I don't know what im doing wrong. Any tips?
