Badges, generally, are stuck to the car using two methods, posts or adhesive tape. Post-mounted badges are easy to remove since they only require a nut driver or the right sized socket, but I've seen tons of paintwork damage done by well meaning folks using metal paint scrapers to get their adhesive badges off. If it's good enough for 'your' enamel, then floss is definitely good enough for your car's as well.
This takes only seconds and makes you wonder why you never thought of it before :)
Step 1: Visit Dentist...clean teeth, score free floss!
Step 2: Now the hard part...
Don't try pulling the floss through, it'll just snap. Saw back and forth to get a good cut. If it does snap, don't worry, you've got plenty more in that little box plus you know where to get more if you run out!
