ok i am not trying to make my car into a caddy, but has anyone had some side to side compare of actual peel-n-stick dynomat verses a spray on sound killer? i see a few company's market both. and for the money the spray on definitely covers a hole lot more for the buck. way easier to get into places like upper floor pan under the petals too. but if it doesnt work so good for ease of install ill take apart my interior and lay down the mat. i am only tring to curb the road noise not kill it but if i need a hole floor of dynomat so be it! i have already finished the doors in Boom Mat(from DEI) and it helped alot, but the cost! GAAH!! it just sounds like the spray would be so much nicer to work with. I have the DEI products readily available through a store here locally so thats what ive been using. taking recommendations for sure!
