I have a MAJOR problem with keeping the lower plastic pieces surrounding the car (rear bumper and side skirts). I was thinking about dipping these in Black with 3-4 coats on. That way when I head to shows just pull it off and wipe it down. I spent a good hour cleaning one side on monday due to some sort of grease. Any thoughts on this? I'm really leaning towards this for the sides due to the back trim isnt as bad. Any down sides for this idea??
