[68blazer]

I used Raptor bedliner spray for my frame, under the cab and firewall. I will use it under the bed as well as in the bed when the bed is ready. if you never get rid of the truck it doesn't matter about the price of the truck lowering or raising, just my 0.02. anyways obviously I am for Raptor because if the area is prepped correctly it is great and you control how thick it's being applied. I want to make sure you know that I applied it myself and because of that if you go my route make sure you purchase the kit with a gun. you will need it. most kits have it with it just fyi. if you have any questions pm me and I can tell you all I know about it. good luck

p.s. U-POL is who makes it
