I Linexed my sliders (installed on a 2000 Taco Xcab back in 2001). I really liked the way that they looked. They were very grippy for standing on to get into and out of the rig. But, they aren't super protective. While doing the Lockard Basin trail between Moab and Canyonlands, I slid into a small boulder. the sliders protected the truck's side, just like they were supposed to, but the rock ripped the Linex right off them.
I would do it again just for the non-slip issue when standing on them.
