if you have swirl marks, you probably should go with AIO first. This skipping AIO debate is pretty hot. I have never skipped AIO and went straight for the SG, but many say it compromises shine and durability. However I do agree with DK, whats the point of using AIO(slightly abrasive) when the paint is new. SG does have minor swirl filling abilities, but it would be good if you could describe/post a picture of the scratches.
