I have used 2 typs from eastwood single part Gator Guard Truck Bed Liner Kit item no: 10129 Z Price: $44.99
2 part Tintable Truck Bed Liner Kit item no: 10258ZP Price: $139.99
sprayed them both I used a siphon sandblaster from walmart on the first one. just cut hose and put it in the can
on the second one I got a undercoating (shutz) gun and sprayed it
the single stage peeled off after a year or so in the sun (this was a floor pan that was primed, leaned against my fence and wasnt touched for a year plus.)
the tintable is looking good and durable but time will tell it is lt gray but you can color it with just about any paint
I can e-mail you a pic of both apllied if you like
