I'd imagine it is just a case of removing the boot lid trim and disconnecting and removing the wiper motor. Then you will need to block the tube that supplies the washer fluid. Used a golf tee in the past, but it is up to you how you do it.
Shouldn't cost to much to get a
badge sprayed black, find out when they are spraying another car in black and get them to do it then if you are friendly with the sprayer. Wont have to buy extra paint then.
