FORD oval emblem badges fading
 

Around town I'm seeing plenty of faded FORD oval emblems (badges) on tailgates. I had a 1990 Ranger that I kept for over 10 years and the emblems never faded. Is this a quality control issue? Are these aftermarket emblems? Some of the trucks look to be in very good condition and newer models. Just curious if anyone else has noticed and if anyone knows why.
