Remove scratches first with sandpaper the finer the better if they come
out with say 600g if not go down to 400 or 320, to polish go up in grit
to 600 or 800g then use a polish like auto 3M polish with a buffer or
drill on low with a pad. Even 4-600 grit and auto rubbing compound may
be fine enough for you and look great. The shineyer you want it the more
steps and work it will be. Just 4-600 g paper will clean it up to satin
finish
