I am very fortunate to have my front bumper/lip to be painted for free by a family friend who works at an Auto Body Shop. He just requested for me to give him the color code of my car and that he'll do it. Anyhow, I won't be around to show him my car (he's gonna have the parts taken to him by another friend) and I was wondering what process for the full paint job of the front bumper and lip should I make sure is taken care of, to make sure everything matches well? Primer, paint...etc.
