So for those of you that don't know second skin is having a black Friday sale through their Facebook starting the 25th at 11pm PST and for the first 30 min everything they sell is 30% off and I'm planing on buying some luxury liner for the entire floor board of my car. I was wondering if anyone that has experience with this kind of stuff knew how many sq. ft. I would need to get? I'm thinking 36sq ft would do it but I would hate to not buy enough then to buy to much.
