Recently a neighbor of mine stopped in and inquired about refinishing the wood slats in his current project. I told him that if he could remove the slats, bring them by and I'll see what can be done. . . He did just that and the next day, he brought me 8, what he thought were Oak boards from his pickup bed.
After running them through my thickness planner, I was surprised to see aromatic cedar boards coming out the other end ! ! ! Some of the boards were in rough shape but still salvageable with a little woodworking magic and a lot of filler.
After prepping them several coats of marine grade spar polyurethane was applied with sanding between each coat. . . All 4 surfaces + the ends. (He drives this truck daily rain or shine.)
