Fiberglass fenders on the street?

I also read that the amount of weight saved w/ the fenders isn't all that much - maybe I'll just go with the hood and possibly bumper.
For the time I have into the fenders, the weight saved is not that great. I got my Scamp to 3036 lbs. But thats what I wanted to do. Every little bit of weight I can cut I did.
