I think Bigmike is right, each shop may apply the liner in varying thicknesses. I've seen bedliners hold up to carbides, and some not.

If you want the spray in liner, go for it. Prior to loading the sled, cut strips from an old plastic bedliner afew incheswider than the sled skis. The grooves in the plastic bedliner create slippery runners for the carbides, and in turn less damage to the bed liner.

 

We have had about a dozen companies here locally come and go:

Permatech
Speedliner
Morton
Scorpoion
Armaguard

But all had one thing in common the warranty was dealer supplied only... With Line-x or Rhino it is Nationwide.... But I found Line-x is way tougher than Rhino it doesnt tear or chip like Rhino. So I choose Line-x

But bottom line is stay away from all no name liners because when they go under your warranty goes under with them. Also most dont and wont post their warranties on their websites....

here is my dealers website check this liner out
