Sherwin Williams TRG103 Dupli-Color Truck Bed Replacement Roller Cover, 4 in.

Dupli-Color Truck Bed Coating is a durable, black vinyl polymer coating that protects truck beds at a fraction of the cost of conventional drop-in truck bed liners. Designed for the do-it-yourselfer, it's available with multiple application methods - roller, spray gun, or aerosol - making it ideal for use as an all-purpose protective coating for truck beds, inner fenders, tailgates, bedrails, cargo vans, step areas, and running boards.
