used the Herculiner kit you can buy at autozone, I took a good amount of time prepping it all. I sanded for 4-6 hours one day and the proceeding two days I would throw coats of bed liner on. I ended up doing 4 coats on the rockers and rear bumper and I think 5 or 6 on the front bumper. I used the supplied roller, I think it looks pretty damn good in person. I never liked the silver two tone etc, as a truck I feel like it has to be murdered out and leveled out with a nice tire on it.Great work on the truck. putting bed liner on the rockers never occured to me before but is good idea. What brand DIY bed liner?
