Hmm lets see , spent $40 on cardstock (couldnt get scaling right ) , $50 on fiberglass resin so far , $30 on fiber mat , 2weeks of time just to find out after fiberglassing suit it was just a bit to small to fit , so starting all over again with slyfos pep and gonna try again still need paint and bondo , leds, fans and visors,so guess if ya mess up like i did a couple times could cost alot.
