HIGH-GRADE FRP Versus Motorsport is one of the first company introduced this material in the American market making body kits in 1994 while many others still using chopper gun method. High-Grade FRP method is using hand-laid fiberglass cloth reinforced with plastic resin and was innovative technology at the time for body kit products. It took a much longer time and a lot more man hours making body kit products with this method as workers have to slowly lay the fiberglass cloth evenly than apply resin on top of it for many layers. On the other hand, chopper gun method is a mixture of resin and chop fiber spray both at the same time using a machine which create a much faster time yet creating a thick, sloppy, rough cut edges and uneven surfaces when making smaller products such as body kits. Chopper gun method mostly use in making huge fiberglass products such as boats, bath tubs, water tanks, etc. Now many places in the United States including California regulation does not permit anymore new license as well as banned this chopper gun method manufacturing since it is bad for the ozone. Versus Motorsport able to create a thinner yet much stronger and lighter products compare to chopper gun method.
