I am blacking out all the trim on my car including the door handles. I am not sure what i am going to do about the door locks. Is there such a thing as black door locks for Z's or came someone point me in the right direction??

Nope I dont think there is, you'ld have to paint them, but I dont think it would last long before getting scratched off trying to find the keyhole in the dark.

Another option would be to delete the locks completely, weld up the holes, and paint over. Put central locking connected to an alarm to lock/unlock the car. Leave the hatch lock though, incase you ever need to get into the car if the battery goes flat, or something else goes wrong.

possibly have them powdercoated??

There is a powdercoater in the group.
