rs2 bumper on a coupe painting advise needed

[220bhp]

My coupe is being stripped ready for a respray, and I am fitting an rs2 bumper.
What's the best way to deal with the fact that the rs2 is colour coded, and the s2 is not.
Do I paint the door trims. Remove them and fill the holes. Or is there another way.
Same applies to the rear bumper. Do you simply paint over the black part of the bumper.
I haven't asked the paint shop as yet, as I wanted to ask on hear to see if there are anyone has BTDT.

I colour coded front and rear bumpers but left the rubber door strips black for now looks OK on mine what colour is the car

Thanks for the advise: thumbs: My car is Emerald pearl. Did you just paint over the black part of the rear bumper.

Yep, well the paint shop did, think it needs some sort of preparation to make sure it has a nice finish that will stay on
