This Tacoma came in for a full exterior and interior. The bed liner is the spot that gets ignored most often, and it is also where the worst buildup happens. Spray in and drop in liners are textured on purpose for grip, and that texture traps everything: brake dust, road salt, spilled fluids, fertilizer, whatever got hauled last. A quick rinse runs right over the top of it and leaves the grit sitting down in the grooves.
Two things happen when that sits. First, salt and chemical residue hold moisture against the bed rails and bolt holes, which is where surface rust usually starts on a truck this age. Second, dragging cargo across embedded grit is what puts the deep scratches in the liner that people assume are just normal wear.
The fix is not complicated. It needs a degreaser with real dwell time, agitation with a stiff brush that actually gets into the ribs rather than skating across them, and a full flush so the loosened contamination leaves the bed instead of settling back down when it dries.
Tailgate seams and the area under the bed rail caps get the same treatment. On a covered bed like this one, the cover itself needs cleaning on both sides, since the underside collects condensation and dust that transfers right back onto whatever you set down.
Same principle applies to wheel wells and door jambs. The areas you do not look at are the ones doing the damage.
