just go to home depot and buy a grinding wheel that looks like it has a bunch of rubber bands wrapped around it,(not sure if the exact name) and go over the spot where the badge was until its almost invisible and then wax it with nxt 2.0 tech wax absolutely mint

 

i used a little carb and choke cleaner to get off some of my excess crap left over, seemed to work well as long as it doesnt sit on the paint too long
