Sorry about that. I didn't realize what the degree of your ability was, but i assure you nothing i told you is anything i haven't done many many times with great results. I assume you ARE wet sanding? And with the proper paper? (wet and dry 1000 grit or higher? You can always go to a courser grit like 600 if you're having a hard time taking it down, then going to 1000 or higher. That'll take anything off and after polishing look like chrome with a richer look. But you have to do it the way i said and be sure to wet sand, not dry. Then a good metal polish like mothers mag and aluminum polish or blue magic. It should be very easy to make it look awesome and far better then stock. Then filling the letters should be dirt simple.
