i have a crx which is quite loud exhaust wise and this winter i plan to put a system in it, but i was wondering if laying secondskin down would be worth it? if so how many layers should i lay? and how much would i need to do my whole car twice or three times? i also saw a product made by ss called overkill, has anyone tried this? i want it to help spl a little but mostly block some of the road noise, and also has anyone used peel and seal from home depot or lowes?
