no door handles or the entire car, but i think i too am going to do the B-Pillars on mine. one of my buddies showed me his car bits he did with this same 3M stuff and i was amazed how CLEAN it looked.
and i was able to get the nice glossy finish with some carnauba wax so im taking off my Evo-R b-pillar (it looks nice but the threads are not as black as i wanted them to be) and replacing with this 3M stuff as soon as it comes in.
