Interior rip-out, Rhino Liner coating

Because then you've got a mess... a crackly mess.

I tend to disagree with your appreciation

Maybe I should not have mentioned specifically "rhino liner". The carpet substrate is a rubber mat. I would say "shave the carpet until you get it down to the rubber", but i'm not sure you can do that. The alternative would be to apply a rubber spray to the carpet an work it into the fibers of the carpet, and maybe do the same to the sound deadening material underneath it.

Will it be a mess? Most probably yes. But, hey, it would look "industrial"
