hi well i will post a pic before and after this is haw i do it on brass ones any way i scrub the brass plate with a scratch brush i will post a pic of that to once all the crap is off i then polish the lettering then i give it a wash in soapy water then i spray the pant on if the lettering is well pronounced all you need to do is glue sum wet and dry sand paper to a hard and flat Peace of wood then rub over the lettering and buff up if on the other hand the lettering is well worn i use a scalpel to remove the pant from the lettering a bit time consuming but will look good when dun this is the before pic of the bit I'm working on at the moment
