a buddy of mine used some sorta spraycan stuff in his TJ, it's already flaking off in some spots, but i dont think he prepped it good enough. also, a guy ina truck forum with me did his truck bed with herculiner, and after his first load of lumber he had some chiped spots, and he says he did extra prep work the herculiner says is necessary. i think i'm gettin mine sprayed with pendaliner at a local truck accessory shop here in town. i know money makes a big differece, and believe me, i aint got much money at all. but i'd rather it be done right the 1st time.
