From reviews pretty much all diy liners suck. There's a couple that have good reviews, raptor liner being one of them. I think I may give it a shot and get a bed mat

 

Have it professionally done

 

i have done a herculiner myself and had 2 rhino liners put in and diy i not worth it. hours and hours of time and a mediocre result at best. well worth the money for a pro job, a far superior job.

 

I had Herculiner in my Ram. After a weekend of work and rushing out to buy another can because I ran out on a crew cab short bed I still wasn't happy with it. There were thin spots, and looking at it wrong scratched it. It also stunk for months. The only pro was that I didn't slide around in it when the bed was wet.

I have Line-X in my screw. It was a few hundred more, but the quality and transferable warranty are worth it. Save your money until the pros can do it.
