Has anybody had Line X installed/sprayed to the floor of their PM? I had an estimate done and it was $500 for the floor or $1400 for the whole cargo area (floor,wall,ceiling) . Idk if this is a good idea except for anything but the floor. Skeptical on the rest. I think the installer is looking at the job will be easier if he doesn't have to tape off areas. Just trying to price out all my options before making a decision. The floor and walls have been priced out at about $1000 or so each from different vendors. That seems pretty high. Installation is what runs the price up. Anyone diy yet?
