Shadow- welcome to Autopia! #7 is nonabrasive, it won't remove any marring. Sometimes you can use it with a slightly abrasive applicator (cotton terry) to remove *very* slight micromarring from old-school single stage lacquer, but even that is *very* rarely (successfully) accomplished. So no, #7 is just "makeup"; it might hide some defects with oils and fillers, but it won't mechanically or chemically *remove* them.
BTW, many of us prefer other Meg's "pure polishes" such as #3, #5, and #81 on basecoat clear. These are also nonabrasive and are similar to #7 but subtly different and more user-friendly.
Lots of info on #7, well worth searching on.
