If the kit is unpainted at the moment, please, PLEASE do not put it on unpainted. I know it's the coolest feeling having a new kit and wanting to show it off, but there is NOTHING worse than a car with an unpainted kit IMHO. I laugh at rice every time I see one. I had my kit since november, unpainted until May, but I waited and waited since I didn't want to be one of "those" guys.
Don't be one of "those" guys, no matter how hard it is to resist.
