The Gorilla Gold felt like a pine-tar product. It made the hand very sticky, it had the consistency of Vaseline and the ball stuck to her hand; flying in all sorts of different directions. Try it first, we gave our supply to the golfers in the group.
We had much better success with a product called Ultra-Grip by Mission. It is a skincare product that is applied to the hands (not on the mound). It increased the grip without leaving anything on the ball or the surface on the pitchers hand; was very useful for those cold, wet spring days. She also used it in travel to combat sweaty hands, not a problem in HS ball.
Gorrilla Grip and rosin is allowed to be on the mound at ASA and NCAA games. If the Ultra-Grip stays in the dugout, leaves nothing on the ball, and doesn't show anything on the hands.... can an umpire rule it illegal?
