I decided to go with the Colgan bra for the front, but I want to have 3M put on my headlight covers and mirrors. Can anyone recommend a shop familiar with Zs in SoCal (preferably Orange County)? About how much should this cost out the door?

 

I would recommend these guys, although they are in Torrance it's a bit of a drive.

Having said that the lights and mirrors are the easiest thing on the car. I guess most places can't screw that up.
