You're right with the Burtin family not being involved in Line-X, they sold it back in like 2005, but they are still very much involved in the bedlining business as well as foaming. But bullet does offer warrantys across the nation, and as far as the tensile tests and the tear strength tests i don't know if i'd believe what Line-X has to say. Even on their own website they lie in the Line-X VS other products section of bedliners. I can't be 100 percent on all of them but I know for a fact that bullet is warrantied nationwide, durable impact resisting, environmentally friendly, tough consistent, provides years of service, available in colors, adds value, and is scratch and dent resistant. Line-X gives themselves checks for everything and other only checks for dampens sound and no lost cargo space. I'm not knocking Line-X, it gets the job done, but since they sold out to a corporation they've been shady.
