Well guy's you may remember that Ss was having a contest on here for damplifier pro pack. Well i was one of the lucky one's and won one. Now i know it's been a while until i did this review but i used it in my girl's install and had to get that done first so i could review it lol. But this product is amazing guy's i've dealt with many other deadners such as dynamat , fatmat , raammatt. second skin i guess you could say kinda close to raammat but just from my point of view its a bit thicker. I used the 13 sq ft i won just on the trunk lid and wow what a diffrence the trunk lid is like as hard as a rock lol. Second Skin is an amazing company and great product keep up the great work guy's. not the cheapest but u deff get what your paying for with Ss
