Well I am assuming you are working by hand, so I suggest trying 3M Swirl Mark Remover (PN39009) by hand to try to get the light ones away. Then use 3M Perfect It II Fine Cut Rubbing Compound (PN39002) for the deeper ones. I am kinda hesitant to recommend 3M Finesse It II Finishing Material (PN39003) because some people have not so good experiences with it by hand, and it is a machine polish.
Follow up the 3M polishes with a quality sealant.
Hope this helps,
Jason
