David Fermani said:It's going to be real hard to remove scratches in that piece of trim. You could shine it up with a wool pad + rotary, but I'll bet the scratches won't budge.
I respect your opinoin but without knowing what it is made from how do you know that?
if it is alum or even SS it will take some work but it can be done
also I would use a die grinder with felt tips
