How far does one gallon go… will it cover the whole bed?
While you might see products at Walmart or other retailers advertising they will cover the whole bed, they simply do not provide protection. A gallon only covers an area with a certain thickness no matter the product. Most of these products are single part products which means they dry, not cure. When a bedliner product dries, it loses a certain percentage by evaporation (making the end result thinner), and many of these products are about 40% VOC (the part that evaporates). All Spray Lining and Coatings products are 100% solids and do not evaporate (they cure), so any of our products will cover almost twice the area at the same thickness as these “one gallon does a whole bed” claims. We do recommend you stick with our recommendation of using more than 2 gallons (final sprayable product) for a compact truck, and at least 4 gallons for a full size pickup to get the recommended 63 mil average thickness to give true truck bed protection instead of simply painting the surface with bedliner.
