it does work real well, i like the 3/8" teflon i work at an aerospace manufacturer plant and have acces to stainless, aluminum, titanium, teflon, heat treated, tempered.....
im going with the teflon if you went off a jump and landed right on it it may get bashed through but so would steel, basicly if your bolts will hold it will too, the only down side is its so slick you cant control your slide im told aluminum is so soft it digs in and does not slide most popular is .120 mild steel (about 1/8 inch)
