colour coding at a body shop usually costs around £200 - £250, i did mine myself, you cannot remove the strips on there own they are part of the arch, lower door pannel and rear 3/4 pannel. however if you are carefull at masking it up then there is no need to remove them. you will need to cover the whole of the side of the car to stop any overspray, also you have to pull out the side repeater and mask it up and remove the door badge. its then just a case of working different grades of sand paper, starting with a relatively coarse one to make it smooth, finishing on 1200 grit. then apply 3 coats of primer, allow 24hrs to dry, then 3 to 4 coats of paint, allow 24hrs to dry then 3 to 4 coats of laquer after 24hrs you can remove the masking tape but i kept mine garaged for a week for the laquer to fully harden
