I want to reduce the road noise in my car but I have no experience with these products. I talked with a stereo rep that showed me some HushMat. it was available in several different thicknesses. The 5/16" stuff was $189 per roll and it would have taken 2 1/2 rolls to do my car! Uhhh.... that seems a bit steep, right?
Anyone here tried this stuff?
 
I bought some stuff off E-bay that is similar to Dynamat W/o the price tag. I got two rolls shipped for $159. I'm putting A/C in my car so I want it cool. Pretty easy top work with and it is heavy stuff.

I have used dynamat and and similar cheaper stuff on my duster.
Covered 70% of floors plus doors, trunk, wheel wells, walls on back and behind kick panels.

Dynamat cost way more but was easier to put on and weigh less.
Car is now quieter than my 05 Volvo v50, even whith droning exhaust on my duster:)
75db at 60mph I am happy
 
HushMat here....works great

Raam Mat cannot be beat for the price. Whatever you decide to use, make sure to use a Butyl rubber product for sound insulation. Roofing rubber is fine below 80* but once it heats up up above 80* it omits a rather strong odor similar to freshly paved asphalt or tar & is not pleasant nor does it dissipate quickly.

GREAT suggestion on the heat/cheap roofing stuff being smelly. I would have never even thought of that!
 
Remember to check your door and window seals. If they are in bad shape replace those, you can remove lots of noise by doing that.
 
I used Hushmat. I bought it from a friend who can buy it wholesale. Look for deals, they are out there. Two boxes got the job done.

How is sound reducing "before" and "after"? Or do you have a good "before" to judge from?

Was that two of these boxes/kits: BLACK, 20 SHEETS -- 12.1 x 23 in.; 39 sq. ft. I see them on Amazon for $150 each.

How does Fat Mat compare: [ame="http://www.amazon.com/Rattle-Trap-FatMat-Install-Included/dp/B003TUNRGM/ref=cm_cr_pr_product_top"]50 Sq Ft Rattle Trap FatMat 80 mil Bulk Pack Install Kit Included : Amazon.com : Automotive[/ame] It's $93 for 50sq ft.

I didn't notice a huge difference in sound, but it WAS parked too long for the interior work to get any real comparison. What I did notice was the reduction in heat coming up from the floor boards. I recently installed a stereo with an amp and can't really enjoy it over the drone of the Flowmasters. They will go when the engine is replaced.

Yeah, that sounds like the boxes I used, but I paid around $100/box if I remember correctly. It's been several years ago.

I don't think you would go wrong with the Fat Mat. My buddy uses the Hush Mat because that's what his supplier has, so that's what I went with.
 
Just one comment...you get what you pay for. Do some research on sound deadening and product comparison. There's a lot of it on the Internet.

I've tried all the cost cutting tricks, but found the best job of quieting comes from the product engineered to do the job. Anything else is a compromise. Your choice.

I thought that might have been a problem too... BUT I live in South Fla where temps reach over 100* at times and I have left my convertible top down with car in direct sunlight. I have never smelled anything since I installed the "cheaper stuff". Note- I do have a sound deadner as well.

Hey... if you got the $ buy the good stuff. If you are looking for other options, the Peel Seal cost me about 1/2 the price and I didnt have to pay shipping. Drove to Home Depot and picked up 4 rolls- had it all in that afternoon. JMO
 
I used FatMat , found on ebay. Worked great and half the price of others. If you use it on overhead surfaces, make sure you clean well with alcohol.
 
I use the quick roof type from home depot never had a bad smell and when I compared to dyno mat they seem to be the same when I took them apart

What stuff have you tried?

What have you tried that didn't work?
 
We used dynamat on the Duster , a bit pricey yes but you get what you pay for ,it works awsome, easy to work with
