i would probably just get that rhino liner kit from autozone and do it up. i think it can be sprayed or rolled. i priced getting my 4dr tracker sprayed with line-x, with me pulling the interior and prepping it, they told me it would be about 700 bucks. that was with them doing the inside of the doors also. i thought it was kinda high especially since all the interior would be going back in it and the line x would be used for sound deadening only.
