Video tutorial on how to refresh faded plastic or rubber trim on your vehicle by repainting it. The particular product I used was Dupli-color Bumper Coating satin black. It tends to be easier if you remove the trim from the vehicle rather than trying ti paint it on the vehicle. If you do leave the trim on the vehicle, you may miss some areas with paint, you also risk over spray, and taping the parts off can be time consuming and tedious. This particular tutorial was done on a 1984 BMW 733i.
