Raptor U-POL Dove Gray Urethane Spray-On Truck Bed Liner Kit with Free Spray Gun - 6 Liters (1.6 Gallons) | DIY Protective Coating for Pickup Trucks, Trailers & Off-Road Vehicles | Scratch & Rust Resistant

I think the instruction are very clear. You do not need a chemistry degree from MIT (go Beavers) The product is sticky messy and do damage to things you love. If your IQ is close to that third digit you can do this. Prepping is the least fun and it is the most important. I sanded my bed paint of my truck to ruff it up. The spray gun stuck with the trigger wide open twice. You need a quick release. The O ring got pinched. After your first coat you are told to wait 60 minutes or 24 hours. It took me the entire hour to clean my gun and hose. The professionals probably have that hose coming from the ceiling. My suggestion is to have a goffer chemist. He can shake the bottle pour in the simple formulas and hold your hose. (Hold your hose is the air hose) Prep Prep Prep Prep. When this starts you are up against a clock. The product is chemically reacting, the gun needs product flowing, and daylight is burningGreat product and I couldn’t be more pleased with the results. I had never done a liner before and it satisfied my needs. I also did an old army trunk, and a yellow piece is Samsonite luggage.
