Pff thats nothing, you dont need to redo the hole thing....
Actually that ne in specific w/o looking at it in person because pictures are deceiving sometimes ok? You have to just sand with 1000 grit wet sand paper and then polish the thing like a madman. Done.
Or do what i was telling you... sand with 600 grit just like 1 ich around the scratch... put 2 coats, 1 light and one heavy coat... then sand using 600 grit sand paper in a little piece of wood to get the whole thing even, once you are right there close... polish... done.
U were here i would offer you to fix that for free...
