I have a resprayed island green metallic 525i
I left the trim black and the lower valences. If I would have painted them they would be all pitted with rock chips by now. The trim strips I reused but recently polished them with a buffer and some rubbing compound. They glossed up nicely and now I never have to use any dressing on them. The door handles are next along with new gaskets.

In my neighborhood there is a kid with a e34 that they painted everything from top to bottom. looks like complete garbage. You have to at least leave the door handles and the trim strip with the reflectors black for it not to look like to brought it to Maaco.
