Spray on bedliners...a few questions

I'm in St. Louis, Mo area, and most places i've talked to are all around the same price, $385-$450. Which i think is silly when u have half the bed or less. We'll see, i might buy the SEM kit from my work and do it or something else.

 Color matched Rhino Lining. Its been in there for six years and it still looks brand new.
