I used 2 cans on my super crew shortbed, minus the tailgate. looks good up until the sprayer (sold here) kept clogging, I would then put my finger on the nozzele and pressurize the can. This caused a couple big seagull turds to shoot out and land in the bed. So then I would remove the sludge can and stick the sprayer in some asetone and try again until it clogged. No idea what was happening, product was mixed well. sprayer sucked.
