Has anyone tried it? If so let me know how much it was and how effective it was.

You're in georgia right? Get Line-X, as it'll be cheaper, and is the same product. My friend used to own a Rhino Liner dealership here. If it's not sprayed correctly, it looks like shat, and is ineffective at anything (trust me, he sold his half tio the partner, the partner didn't go to the Rhino School to learn how to spray, just figured he could do it. Yeah, everyone he does looks like hammered ***. He bought the first guy's truck he messed it up so bad). Anyway, the spray in bed liner is a good idea in the trunk, however, I'd recommend going with a rubberized undercoating, or just buy spray cans of spray in bed liner. You can "deaden" the spots you want, and not waste product or money, as spraying everything won't do much. Before spraying anything, I'd foam the places that can be spray foamed. Then, I'd spray everywhere panels, or pieces of metal contact each other. After that, mat dampen over all of it, to ensure full deadening, then maybe spray another coat over the mat deadener. deadening.

I would put mat deadner down first, then spray.
