Apply masking tape around your existing badge, to ensure a perfect alignment, place the tape at the bottom and sides.

Use a heat gun or hair dryer to soften the glue on the old badge.

Use dental floss or thin fishing wire to slide behind the badge and easily remove it. 

A plastic card can also be used to help prise the old badge off.

Thoroughly clean all glue, grime and residue from the area. 

High alcohol based cleaning solution, soak the glue in your chosen product, leave for 5-10 mins, use a microfibre cloth or buffer for best results.

Ensure area is completely dry and free of any dirt. Then peel off backing film and align it with the masking tape, press firmly and hold making sure all sides are making contact.
