I have used four of the kits,
one for my daily drivers 6ft truck bed,
one for my wheeler, used it on the floor and inside the fenders, bumpers etc..
one 1/2 kits for my 18ft flatbed trailer, rolled it on the pressure treated boards on top and used spray cans underneath, and rolled it on most of the edges where you would step on
the last 1/2 used on my luv's bed, yea it was only 1/2 left from trailer but was enough to do a lite coat.
its nowhere as thick as say a linex or any other "professionally" sprayed on liner but for the price you cant beat it
easy to use, I did it outside in the driveway, hardest part is the prepping. I bought as cheap as $55 for kit(on sale plus rebate), the most I spent was still inder $100
If you want it a little thicker buy the extra can, I did this on my daily driver after about a year of abuse
