The coating texture in my bed is like sandpaper and whenever
I'd slide anything in it that was painted, it basically sanded the
finish off. When it started to affect the camo finish on my tree
stand, that was the last straw. My last truck had Line-X and
it was far better than what I have now. I have the Utili-track
but have never used the bottom rails. They're nothing but dirt
catchers for me, especially after hauling my ATV. I solved the
abrasive problem by putting in a moulded rubber bed mat. Not
only does it smooth the bed out but adds additional non-abrasive
gripping. Air can still circulate and its easy to remove for
cleaning the bed. It's cut to fit the Titan and cost $69.95 (includes
shipping from tonnocover.com). It's the "Driver Design" brand.
That coupled with the Truxedo tonneau makes a nice bed!
