It would look good, just take your time cleaning it off and make nice even coats. I actually used plasti-dip on all handles, sunvisors, sunroof switch, and door handles on an older Volkswagen I used to own when I did a black headliner.

Plasti-dip is definitely tough and made to be touched, so I wouldnt worry about that. I would remove whatever you are planning on spraying from the car so that you dont overspray though.
