I just need some deadener, preferably enough to do my whole trunk and doors (2000 Pontiac Grand Prix). I don't want to pay the outrageous prices at my local shop.
Peal N Seal isn't meant for vertical surfaces, it's meant for a ROOF. Honestly just don't be a cheapskate and get real deadener the first time. If you don't make time to do it right the first time, you'll just have to make time to do it again. 40 sq. ft. of Second Skin is around 120$ shipped and it's more than enough for a trunk + doors.
by the time yopu put enough peel and seal on your trunk to suffice you could have bought some ss damp pro and be done with it with one layer! shits the best!
