I’ve used it, I picked up a set of 6” fenders for my first project years ago at off road expo in Pomona. The glass was decent, nothing special, I would say Check and see if they’ll be at off road expo and if so maybe call in and order what you need and try to arrange for pick up there (if that’s doable for you)
Another good place to check is off road swapmeet at morongo casino in Palm Springs, lots of fiberglass gets sold there
