[header] How to debadge your car [title] Determine how the badges are fastened to the vehicle. [step] Many automotive badges are held on with a simple adhesive, but some utilize clips or rivets that pass through the body of the vehicle and can leave holes behind. The way the badges are fastened will determine how you go about removing them. 
If your badges include clips that fasten to the body, removing your badges will require body work that includes filling the holes and repainting that component of the body of the car (at minimum). This should be done at a professional body shop.
