If you are going to use bedliner you have to use the good stuff. The cheap stuff at parts store etc is crap. Sorry but it fades out, looks bad, some looks like the dog threw up on whatever you painted it with. LINE-X and the other major brands charge what they do for a reason, it looks good and stays looking good. Heck check out TJKJs. Troy used a more expensive type ( not the most expensive but lots better than the spray can junk) and many years later it is still looking like he did it yesterday. My buddy Chris had his Line-Xd and that was 5-6 years ago and still looks new
I dislike all of the plastic dipped stuff folks are doing, BUT have to say I did my flares as a test and now two years later the dang stuff is still on there. Of course mine never goes through any kind of high power car washes except to spray the undercarriage
