painting my 71 dart bumpers...

alright i think ill keep the bumpers the way they are. i have no idea how to revive the shine, nothing has worked. no the chrome is not flaking off but where the water runs off the hood its a dull flat spot on the front bumper, they just look worn. it was something temporary, but if it will be a problem when i strip them down to chrome again, than old worn chromw bumpers it is! thanks
