Weel, it is CLAIMED to be as good as Dynamat... Anybody can claim anything they want... Is it as good? It seems as though they offer a warranty on performance, so give it a shot!

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

A bit of subject but I just got some undercoating spray (it says it is used to sound deaden as well) $2.68 per spray can from WalMart (can is bigger than Dynamat and weighs more by hand feel).  The Dynamat spray is $25 at Tweeter (online may 10+ 5 to ship).  I'm thinking this product from WalMart has to be close to 90% or more as effective as the Dynamat or smilar product but without the price markup.  I'm doing to door panles tonite (1 can for each) and if it works well I'll keep using it.

Please let me know how it works. I would go and buy some can right away if it works for you. Let me know how thick it is when applied. Thank you

It is thick.  One coat is 75% the thickness of a regular folded paper knapkin.  At first I did not shake the can so it was coming out like paint (then I read the DIRECTIONS) and shook the can for 1 minute.  It came out textured and thick.  1 can can do 4+ coats on a door panel.  It dries pretty well in about 45 minutes.  I can definetley tell you it works.  I was driving today and normally cars pass you by and you can hear them (faintly), now they pass by and nothing is heard, this is also in 98 camry which is kind of quiet to begin with anyways.  Get this, you won't be dissapointed.  I'm getting more for the trunk.  WalMart $2.68 a can.

Wanted to add that the total thickness with 4 coats was the same as 3 or 4 double folded paper knapkins.

McMaster-Carr has an asphalt-based sound damper sheet, 36 sq. ft. for about $42.  If you're interested I'll post how to find it, as it is a PITA on my part.  Oh, here we go, a search through the forum was the easiest way:  https://www.the12volt.com/installbay/forum_posts.asp?tid=33610&KW=McMaster%2DCarr

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

So I have a question for anyone who has used these products...

Is is better to just use the spray stuff for everything like the trunk or does the sheeting like Dynamat and B-Quiet work better for the trunk and flat spaces.

I would think the undercoating would be easier to apply, but does it make a mess where you don't want to touch it?

I am at the point that I really want to start doing this sound deadening thing in my trunk before I put my finished boxes in, and I would like to have the easiest, but still the best prduct.

P.S. ~ I would rather sacrifice ease for a better working product anyday, but a little of both worlds would be nice.

Anyone have any opinions on the subject?

I just got some of this
It works really good and is easy to work with. It doesn't smell bad either. And I only paid like $118 for 100sq.ft. shipped. Thats 2 rolls, each 18" x 33'. Enough to do 3 coats in most spots.

The post I made above is actually on page 3274.  It's .07" thick, or 70 mils.  Good stuff.
