Sorry to correct you but FRP is not the same thing as fiberglass. Fiberglass is glass fibers suspended in a resin (acrylic?). FRP is fiberglass reinforced plastic. Instead of the two component thermoset resin, you have thermoelastic plastic. In other words, you can MELT FRP's primary constituent but you can't melt fiberglass. FRP is a newer tech than fiberglass.
