Hi all...I don't know how many people on this site ever considered adding insulation to their vehicles but for those of us who have, the difference is amazing. The BEST stuff out there is the batt sound absorber developed by 3M. I was able to buy some of it a couple of years ago (from a marine supplier...who no longer carries it) and used it in my Honda Accord. High-end car makers (Acura, BMW, etc.) use it because of it's light weight and effectiveness. It is a phenomenal sound absorber and also adds thermal insulation. Although I did a complete installation (behind the doors and all interior panels...didn't do the headliner), adding this stuff to problem areas (doors in particular) will decrease noise levels a LOT. The Honda was luxury car quiet when I was done (VERY noisy before)...the new owners commented how quiet the car was when I sold it (they looked at me like I was crazy when I told them what I did to make it that way).
Up to this point, it was not available to the public but in my searching I see that someone must have gotten a quantity of it and is reselling it on Ebay Motors. Looks like it comes in a minimum quantity of 25 ft. long by 5 ft. wide (with additional quantities available). It's also the good stuff...2 inches thick (which is what I used) vs. the 1 inch version. From what I can tell, their pricing is about 1/3 of what you'd pay (even if you could get it) from a marine wholesaler (the only place I've ever seen it sold...and only in 90 ft. rolls...but they won't sell it to individuals either).
This product is LOTS easier to work with than other products (forget "dynamat" type products...they're only intended to reduce vibration on metal panels...they don't do much to reduce overall noise). I'm going to place an order while it's available (don't know how much they have).
I don't know how to copy the link but if you search Ebay Motors for "3M thinsulate acoustic" you'll find the ad.
