I did it in my TJ and I think it's great. I don't think I have as much noise dampening as I did with the carpet, but I'm not worried about that. If/when you do your jeep, make sure you stuff tape into any bolt holes you plan on re-using. Otherwise you'll be chasing holes with a tap. I covered wires I had running along on the floor with duct tape and then sprayed over the tape. That way, if I have a wire problem, I can cut the duct tape open, repair the wire and then re-apply bedliner over the tape. Probably not a needed step but I wanted to make sure. Surface prep is your biggest concern. Make sure and take your time, other wise the bedliner won't be very durable/last very long. I gutted my interior and sat in there with a DA and a roll of sand paper discs. Take your time, get all the small cracks and stuff and then take your time wiping out the interior prior to spraying.
