Yes I've used Second Skin for my build. Your better off using Damplifier Pro but see if he has some B stock in. It's the same as the regular but has a few manufacturing or shipping flaws. Nothing to worry about.

The Luxury Liner doesn't self stick and is to be used behind panels or headliner. The damplifier to great, comes in 1'x2' sheets and just sticks down. Plus you get 20 sheets for $80. I used 2.5 boxes on mine but could get away with just 2 boxes as I did my trunk also.
