Escape2Powder lined the tunnel/boards on our XLT RMK's back in the mid 90's. When it was cold, the stuff was hard as a rock and like standing on ice. Once the coolers warmed up under the boards, the lining became soft and tacky. Once they warmed up they were great, but sucked when cold. That being said I'm sure the material compounds are much different today, but may have the same effect.
Great looking sled!
