I was reading an old post yesterday the poster said they used a blow dryer to heat the "Fit" logo as to weaken the glue I assume, then they used dental floss, but they recommended using fishing wire instead b/c the floss kept breaking.
I guess by heating up the logo the glue loosens up then u take the fishing wire and try "flossing" it off, from what I remember once heated it comes off, and any excess glue residue you can clean off with goof off. Then leave it de-badged or put the Jazz logo on.
I couldnt find the exact thread but I found a thread which shows you how to remove the H logo's and switch em out for the red H badges.
