I hope it's OK to bump this, but for those who have done Fatmat or similar, how much did you need to get? I have an 06 GT hatchback and basically want to line the entire interior (the best I can, anyway) with Fatmat. I'll definitely just do it in stages, not all at once, but depending on the cost I might just get the whole roll at once and see where I'm at. I'm planning on the entire rear hatch area, roof, side panels, and ultimately the doors. Just putting together "shopping lists" right now and curious what I should plan for. Thanks!
