Lately I've been recieving many PM's about what this is. Basically the GT logos on our cars have the GT in chrome, and the surrounding piece is black. Just carefully apply acetone to the black, and it comes right off! It leaves the GT emblem with a full chrome look. I have yet to see another GT with this "mod," but I love it because it is very distinctive. I just felt that the black outline kind of dated the lines, and never once have I wanted to change it back.
