Herculiner. Paint on. Spray on. ( key words)
A year ago I researched here on do it yourself vs professional spray on bed liners. I did mine myself using herculiner.
Lessons learned. Prep is important. Pressure wash throughly. Clean upper corners before starting. A big can of acetone is a must. The provided scuffer is adequate. The provided Roller and pan are great additions for the trash can. Get a 2"x 6" board to kneel on that fits in the wheel well slots. As the instructions say put on a thin coat. Let dry. Second coat get a 4" brush. Keep a stir stick in the can. Just stir as you go for best results. Just dip brush in can. No pan. I have a quad cab. The gallon can was adequate.
Other notes. The drain holes allowed enough to drip through to stain my drive way. Don't forget or plug up the drain holes at the front end. The rubber plugs don't seal well afterwards.
I used edging tape. Including over the screws on the tailgate.
If I used my truck commercially I would have went for expensive spray on.
I ve hauled mulch. Fencing. A tool box ( always). My liner is holding up.
