The only way to properly remove the scratch, and fully restore the surface is with a decent polisher and cutting compound.
Thank you! I have recently seen dozens of posts advising the use of Turtle Wax products. For one, there is no turtle wax product worth purchasing that you could not get from another brand that works better. Compounds are meant to do heavy cutting, and if you use it, you will effectively be using 2000 grit sandpaper on your finish. Then you will need another polish to remove that, and so on.
To the OP, post pictures if you could. Some scratches will require a repaint, others machine polishing, and others hand polishing. If you do go get rubbing compound, just be warned you are creating a much bigger mess than you know. It may look good, but the compound will induce millions if micro-marrings on the finish.
