I bought this kit from tptools.com and from what i have seen a lot of guys have done there entire bed of a tacoma with 3 bottles having some leftover. A bottle is 26/piece for 750ml then liter of hardener is 30 that can do 4 bottles, gun is like 15-20, i paid 108 for the kit with 4 bottles of liner, a liter of cola, and the gun so i'm probably going to do it a little at a time and probably just order another kit after i get the bed done since it's cheaper then trying to buy it by the bottle. Free shipping and i buy air tools and stuff for work from them a lot.
