do-it your self bed liner

Last summer I did the bed with Dupli-color Kevlar roll on.
It looks ok.
To be honest it is not that durable.
A gallon only goes so far and the coverage is not that thick, and I have a 6.5' box.
It can scratch if you throw stuff in the bed.
If you want it to last I would get the professionally sprayed on stuff.
It is much thicker, maybe a 1/16" thick. But kind of pricey.
