If you're looking for a quality product, I have had Toff spray-in liners in both my '97 4x4 and my '05 4x4... both were sprayed in at Lewis Dodge, in Hays, KS. They did a phenominal job; the kid who does them is anal as hell and takes his time to do it right. The product is pliable, has good grip if you want (he can spray as much or as little grip, after the base coat is sprayed on), and lasts. Cost me $450 each time.
