i took my purple rails off and turfed onto the actual fiberglass rails (filled all the mounting holes with epoxy)
the chin pad, i removed the original covering, and glued the hydroturf to the styrofoam. ive seen a guy remove the styrofoam and turfed just the plastic mold piece...not for me, but to each their own.
the first time i turfed my ski i only put padding on the bottom, and i rode barefoot until i wised up and started wearing shoes when i rode. i just got done turfing mine and this time i padded the ENTIRE tray: bottom, sides, tops of sides, tops and bottoms of footholds, and dash area. makes the footholds a little more snug though, so make sure u got the room to do it.
