For the bed of my Ranchero I epoxy primed it with Kirker Euro Epoxy, then 2 days later Scuffed it good with 220 and applied Duplicolor bed liner. I brushed it on right heavy and let it set 30 min then took the textured roller and went over it again . Took about 1.5 gal . It really looks better than the pic shows.
How it will hold up ?? Don't know but don't expect to be hauling much in it and it will be covered all time .
