I've been looking into sound deadening.

Is Fatmat any good? I can get it cheaply and apparently its not too bad but does anyone have it?

Never heard of it... :confused:

Got link?

Preferably you want something heavy, thats tar/bitumen based with a foil backing.

this isnt the stuff thats about 10-15mm thick
combined with foam, installation sheeting and tar base is it?
its about 3 layers of foam and 4 layers of installation foam combined into one

if its the same one i have.. then yeh its pretty good stuff... its only a few mm thick....
i did my boot lid and it feels much more solid... and took away a few rattles 2

If its foam stuff without any tar then it wont deaden your doors, it will stop reflections. not entirely useless but in a car you want to stop rattles and resonance of 'flimsy' panels. The only way to do this is to brace them (usually impractical) or to add weight to them and decrease their resonant frequency. Tar based deadener is good for this as it absorbs all the little resonances and turns this sound into heat. Spray/Paint on deadener is also effective as it adds weight.

You can add all the foam you want and a door will still vibrate / resonate

Got any pics/links for clarification?

yeh mine is a tar based thingy.... and it sticks like Sh*T and it did add lots of weight....
ur not buying this off ebay by any chance?
