Scorpion Liner. Done the hinges in them as well. Well a buddy of mine did them. Scorpion Liner is more rubberized and flexes better than regular Bedliner so it don't chip and peel as easy. I previously had some Bedlined ones and they didn't last that long, maybe 6 months before there was some peeling starting to happen. I've had the hinges done for right at a year and the fenders for 9 months and they still look as good as the day I we did them. He added some metal flakes into the mix to give them a little more texture.
