Are you talking about badges that the dealer puts on, or badges that come from the manufacturer? It really bothers me when dealers put extra stuff on the car. It never looks professionally done, and it takes away from the clean design of the vehicle.
So how exactly can you debadge the Lincoln and the mkz badges on the decklid? Use a heat gun and pry the adhesive? I've seen badges on newish cars where they were like riveted in and made holes when you removed them just wanna make sure before I take them off..
