Off Road,
You're right! No one has the correct paints for bumpers, but I'll bet the body shops have them! I posted my message because I refuse to pay an auto body shop $200 to touch up the bumper with an airless sprayer! They'd make a couple quick passes (30 seconds worth of work) and charge $200! I'd buy the paint from them for whatever they wanted but I'm sure they wouldn't allow this. I'll do it myself and try the Mothers back to black and see what happens.
I wonder why we have no faith in body shops?
