[QUOTE="Anthony Collova, post: 6967735, member: 558844"] And your comments will still be wrong.. I am not saying that you should stick your car in a -40 degree garage. Anyone with half a brain could see that. I am also not comparing the best coatings with the worst cld mats. Apples to apples here when it comes to performance though. Here are the facts -40 degreee butyl will perform the same without a foil layer as room temperature butyl with a solid constraining layer do to the temperatures effect on the the hardness of the butyl. Vibration coatings have the same hardness and elastomeric value at room temperature as -40 degree butyl does (w/o foil) Therfore, vibration coatings [B]at room termpature[/B], will perform very close to constraint layer dampers, with foil [B]at room temperature[/B] Your idea that coatings work better as barrier is flawed as well. Sure, the will help since coatings and MLV are sol similar in formulation and weight (when applied thick enough) but without a decoupler, you don't get nearly as much airborne noise reduction, you will however get more than CLD mats since the complosition is so much different. This is where coatings have the edge over CLD Mats. Great vibration damping, plus the added benifit of [B]some[/B] airborne noise reduction. Before making your mind up, Go buy some noise coating and test it out for yourself See how it compares to what you have used in the past ANT [/QUOTE]
