So I just finished with the sound deadening of my car. Wow what a difference! The reason I created this thread is to give anyone who is thinking about deadening doors or floor a new suggestion. A friend had told me about a product called peal and seal. It is a cheap alternative to dynamat. Its easily sourced at Lowes or depot (aluminum backed roof flashing) and it does the trick for 3.8% less cost! $16.00 for 8"x25' roll. Dynamat is about $58.00 for the same square footage. I was a bit leery at first as it seems a little ricer but my friend had it in his car "66 mustang" for the past 3 years with no issues at all.
