I would like to sound deaden my hatch and have seen happy people with the quality of your product. I don't know if you're still doing the free samples but id like to see and understand the difference of the 80mil and the butyl. A quote on enough to do the hatch of both the 80mil and butyl please.
Also I noticed people saying something about double layering materials in general. Is it a huge difference or overkill?
Thanks!
