On my old silverado I used a DIY roll on Herculiner from Autozone, total crap...Faded and its peeling off, very thin.
My new Denali has a thick spray on LineX, my old Denali had a Rhinoliner, both good.

 

Went line-x route with it. I had it color matched and love it so far.

 

I used a local brand in AZ called inyati and i really like it. Here are some pictures... I did put a protecta bedmat over it as well... I didn't do over the sides, but up to the top and over the top in the middle panel. Also I got the dealer price of 315 or so and then I had a 225 credit so it ended up costing around 103 out the door. They are pretty well know in the phoenix area, but the pictures should show about how thick it is. Also I did some spray bedliner in the wheel wells under the factory plastic covers.

 

Although OT in this thread, I’ve done Line-X, Rhino and drop-ins in previous trucks. Each had its disadvantages IMHO.

Very pleased with the performance and appearance of a BedTred this time ‘round (with subsequently installed BushWacker rail caps).
Highly recommended.

 

That looks nice on your truck. I llike the panel near the cab, looks really good.

 

you should get some factory rail caps

 

Line x here. Still looks and works great
