No it has always been on it. The hotrod logo is printed on a thin lexan sheet along with the color and it is glued to the top of the hotrod. Not the thick lexan that is used on cabs.
To quote Hanaho
Ok, here goes... The material Hanaho uses is called GE Lexan 10 mil Suede/Mat Polycarbonate. It comes in clear transparent rolls, and the printers print the graphics (silk screen) on the back side of this. By printing the graphics on the back it insures that the graphics WILL NOT rub off. Once it's dry a 3m adhesive is added, then cut, packaged and shipped to me.
