IIRC, there are two holes behind every emblem. I blacked out all of mine. I just sanded them down and cleaned them really well with alcohol and spray painted them with 3 coats Rustoleum semi-gloss black and 3 coats of clear coat. They lasted the harsh Cleveland winter pretty well. But I removed them every spring and repaint them. 3M tape works wonders and is easily available at local auto parts stores. But I also used clear silicone on the pegs on the back of the emblem and around the hole to keep out rain water and to prevent rust.
