my brother bought a Gold VL Calais. The old owner had the car resprayed, but they didnt spray the two tone black back on the front and rear bumpers. so he wants to get it sprayed back on but he doesnt know the exact size it is from factory. if someone could measure it and give me the height it would be much appreciated. (reference of black two tone)

Lol get some black electrical tape and dummy it up. Or Judging by the picture of platinum, the thickness of the black line one the corner of the rear bar is as thick as the mould under the light. So measure the mould, apply the measurement to the lower bar, then draw a strait line from that point to the wheel arch. Do the same for the other side then join the lines across the rear bar. Not rocket science mate. Prep it n spray mat-black

Off memory, its about the same size as the side skirts.. The front was roughly the bottom lip of the bar, and don't paint it matte black, its supposed to be gloss or satin.
