yeah you dish out hundreds, maybe thousands for dynamat, or search ebay for slightly less expensive stuff that is probably just as good.  ------------- 99 Blazer LT. Yellow Top. Big 3.

Basicly consists of asphalt, rubber type material, aluminum cover, or a combination of all of them. Basicly, you can find a less expensive way that works for you, or spend about 120% of your audio budget on deadening

is your goal to reduce road noise, panel vibrations or both? as a general rule increasing mass lowers resonant frequency, as does increasing rigidity of panels. ensuring your weatherstripping is in good shape will help with road noise.

you can go to your local home depo or lowes. they have this stuff that they use on your air conditioning lines so they reduce moister. its like a tar like matrial. its very cheap and does the job great. i have a 03 durango and i used it on my roof and back panals and it works like a dream. huge difference. i think i paid like 70 bucks for everything. deff try that before spending an arm and leg on dynamat. theres this other stuff called b-quite you can find it on ebay its real cheap to and its the same stuff.

Spray on truck bed lining works very well.

jl_jeep19, if you were capable of manufacturing your own you wouldn't be asking how to do it on an internet forum. Buy it like everybody else does.

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

I would agree, people have been using 'peel'n seal' forever. Moat of that stuff will do the trick. Dynamat is nice, but for the money it's a little overboard.

I used a water soluable putty-like roof sealer from Lowe's. It comes in a white bucket from the AC installation and accessories aisle - like 5 pounds for 6 bucks. (Don't bother trying to look it up on their website, as the Lowe's website is the biggest turd I have ever seen, as far as search capabilities.) It's white, fibrous, sticks to ANYTHING (permanently), cleans up with water, and is non water soluable once dried. Dump it a bigger bucket, and mix in silica sand - A 100 pound bag of that'll cost ya like 3 dollars... I used a 50/50 (by volume) mixture, and it works like a champ!

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."

Can you further explain this? Where you put it, its strength when dried. Did you use it for deadening, or for giving your panels ridgity? For putting more mass into my panels, i use "Great Stuff" brand expandable foam. I have a van so ive already gone through about 20cans, but for a car, just putting it in some problematic places, youlle be happy with the results. Its usually 4-5dollars a can. You can also use a Green Can brand from Wal-Mart, which was only 3 dollars a can. ------------- Govenor of Jimcinati

Go to raammat.com and get some of that.
I searched forever to find the right stuff and ended up buying this. It's rubber backed, not tar, so it doesn't smell, and it sticks like mad! You actually need to make sure you want it on something before you put it on. Some paint thinner will dissolve it and release it, but I haven't tried that, only to clean my tools.
Expanding foam helps to fillthe empty spaces that can cause wind whistling and things like that, so you can put that in your rails and such.
I wouldn't recommend truck bed coating, it does not have enough mass to it to make that much of a difference that this other stuff will, I had it on my doors first and still had to go with the raammat.

if you are looking for some cheap alternatives, then try these solutions: a dynamat replacement is to simply use roofing shingles applied with roofing tar. this is all dynamat is, dynamat is just in a sheetform with an adhesive backing. to silence road noise, use carpet padding (yes, the stuff under the carpet in your house). install it under your factory carpet with the bonded side up ( one side will have a clothlike clear webbing attached to the foam and the other side will not). i actually used this method to quiet a notoriously loud mustang that i competed with many years ago.

ok, it looks like im going the b quiet route. What do you need a heat gun for? For working it in the corners?

My friend's got rolls and rolls of this neoprene mat stuff, he says he used it to deaden his old pickup, I wonder if would be good enough to deaden my taillights? The mat's about 1/8" thick, i think
