Since the trim is stainless, if the scratches are very deep they will be difficult to get out. I recommend watching several YouTube videos on polishing stainless and using the sanding process if needed, but be prepared, it is a process!
You will need a bench type polishing wheel that operates at the proper RPM. (A bench grinder will not work), two types of buffing bonnets for the wheel, a couple different types of polishing rouge and about three grades of sandpaper. The more work you do with the sandpaper, the less effort it takes on the wheel.
Also, you can get everything you need to do it yourself at Harbor Freight, or you can pay more and order it from Eastwood.
I did all of my trim myself and it turned out like new!
