Just wanted to share my experience with Raptor bed liner.
I use and abuse my truck bed and have been neglecting spending $600 bucks to have it done professionally.
I finally decided to try a DIY product. The Raptor kit seemed like the go to. 4 bottles plus spray gun and done in about 8 hours total. I spent about 4-5 hours on prep, wash, degrease, wash, sand, wash, fill a ton of holes(previous owner had something mounted in the bed), sand, self etch primer, acetone wash....you get the idea.
I spent about an hour taping, removed the tailgate for ease of complete coverage. Sprayed the first coat medium density in about 30 minutes. Waited an hour, sprayed second coat thicker and then went over with a quick 3rd overspray coat to cover anything missed. Removed tape after 30 minutes before it hardened completely.
I've been using it for a month and its seems tough as nails. Looks just as good as my buddies line-X.
If your in the market this product is great to use.
