we did ours abou a month ago. MAKE SURE TO CLEAN THE SURFACE VERY WELL BEFORE YOU PLACE THE 3M TAPE ON THE LETTER AND ASLO THE GRILLE.
Glass cleaner or alcohol will work fine.
Also be careful when scrubbing the front end once they are on. If you catch them just wrong with the sponge, you can tear them off.
mine came with the 3M tape on them already so I just had to clean the grille well.
GREAT/ CHEAP upgrade!
