OK, Just booked my Grey small bumper 8v in for a respray on the 1st september because the lacquer is coming off and there are a few rust patches

. the body shop guy said he could colour code my sills, arches, and door trim for no extra cost but not sure if it will look ok. would i need to do the bumpers as well or should i just leave them as they ain't in bad nick, should i remove the black tape from around the rear screen and should i remove the black trim from above the rear number plate?

i have already removed my wing antenna and filled it ready. if anyone has any pics as well as advice it would be ace.
