So im trying to make my build sound as clean as possible..even though its in a station wagon k still want to hav everything 100 percent coverage on all doors..the trunk door and trunk area and most of the roof.. ill probably need about 150-200 sq feet or more. PLEASE DONT TALK SHIT.but I habe been using fatmat for a while now. Ive used it in about 5 different cars and have had pretty good results up until now. Double layer on the trunk lid single layer every where else. The last car I used it in was my 2004 impala and guess what? It didnt do as well as the others. Still getting trunk rattle and flex although drastically reduced still present. And its killing my sq outside the vehicle. So I want second skin damplifier pro for this next build but since I will need so much of it I have to know WHEN IS THE NEXT SECOND SKIN SALE COMING UP? I can wait ..im patient. Jus5 have to know so I can buy it all at once might just shoot for 200 ft and charge to install leftovers in other ppls cars
