... Drilled for nutplates for EXPBUS and riveted the nutplates I could use the squeezer on. Polished the Left HS and it looks very good. Used METALL that I bought at OSH and it does an impressive job of rejuvenating the alum. especially with a little metal polish to clean us streaks and the rivet lines. It will suffice until after I am flying and have the luxary of polishing with Nuvite.
