what about that fat mat stuff they sell on ebay ???

 

With that kind of comment, either you were trying for some type of sarcasm, or you must sell this stuff!!!

Sorry to burst your bubble, but you can buy Dynamat Original for 1/8th the price at mcmaster.com It's called hi-temp mastic, and the only difference between this material and dynamat original is the silkscreened logo!! I have both materials, and they are identical down to the terrible smell that they leave behind along with the blue backing.

What really happens is Dynamat buys in bulk, get's their logo on the product, puts it in a pretty box, marks it way up and then advertises in a specialty market. The only reason Dynamat has such a large market share is becasue they had the first mover advantage...they were the first people to really get out there and let potential customers know that this type of product both exists and is essential to any serious installation.

It's pretty similar to how Coke is actually a brand name, but it's used to replace Cola. Same with Band-Aid and bandages, Kleenex and facial tissue, or Q-tip and cotton swabs - you can find plenty alternatives to all of these products...same is true for Dynamat and mass loaders.

So there are a lot of alternatives to dynamat that are more cost effective.

When you are searching for a mass loader, look at the following properties:

1. Density - the more mass you can get down without adding too much thickness allows you go the the car back together easier...this can also save you from multiple layers
2. Adhesive strength - especially important on vertical surfaces or places like your roof. Some materials need a heat gun or hairdryer for proper application, others you can just peel and stick
3. Pliability - you want to be able to work the sheets into the details of the panel you are working on

Past those three attributes, cost is the only other real characteristic of these mats. There is no voodoo magic going on here, just the addition of mass to you panel to lower the resonant frequency.

I use Raammat60. ( http://www.raamaudio.com ) Rick is an excellent guy to deal with. Cascade, E-Designs, Stinger, and Rf are just a few of the manufacturers to make mass loaders in either mat or spray form. You can also go to a local home improvement store and try some of the roofing materials that they have. ONe popular one is called Peel 'n Seal.

Basically anything that sticks to your panel and adds mass can be considered an alternative to Dynamat, only some work better then others.

expanding foam.. $3 can
suran wrap (thick) $2 a box

take everything out of the car, use the plastic wrap on places that you might want to get to later in life (behind dash, between door panel)
then spray away..
put everything back, cut what you dont need, sand what you might see,
half the weight of Dynomat (or other rubber mats) and just as good..

also, you might spend $50 on your entire car..

how many square feet of brown bread do you think it would take to cover all the doors and trunk of a 4dr teg?

 

PROCON from select products is the best I have ever used but its not to cheap. But I agree with the guy who said you get what ya pay for. Take my advise and use a good quality sound damping material. If you dont use a good quality damping material you might as well not use any at all, as the cheap stuff doesn't work at all. I have used all kinds of the stuff and PROCON is the best to my taste.

 

Can you please explain this statement to me. I'm very intrigued to find out any reason why the cheaper alternatives don't work.

Until then, I will keep using my cheap Raammat that "doesn't work at all" and you can keep emptying your wallet for overpriced mass loaders. Until Dynamat Extreme, etc can get competitive with their prices, I'm not going to waste my money.

 

Probably around 60-70 sq ft. for a 4dr.

I just dynamat'd my hatch (96) and it took 10sq ft for each of the rear quarter panels. 35 sq ft for the "trunk" floor. That's covering the entire inner surface though; wheel wells and everything.

It's a very noticable diff. the whole car feels better. You can hear the difference when you close the doors. sounds like a much more expensive car now.

 

Another sound deadening technique I'm trying is to pull out all of your interior plastics and spray down the backs of them with rubberized undercoating spray. You can buy the stuff at Home Depot, Walmat, just about anywhere. I bought 3M brand and it was about $8 a can. I figure it will take about 6-8 cans to do the entire interior (they don't last as long as you'd hope)

 

yuhp

 

3M makes the best undercoating that I have found from an appearance standpoint. If you are doing the back sides of your panels, get the cheap stuff

 

DON'T use rubberized undercoating!

I made that HORRIBLE mistake...the stuff NEVER fully dries.

In the summer, you get in your car and about pass out from the overwhelming smell it produces when it gets hot again.

I'm stuck with a whole car full of it, and there's no good way to get it out. It makes me hate my car

I'm hoping I can get the real sound deading spray and maybe spray it all over everything and hope it seals out the old stuff/smell.

 

Home Depot sells a frost gaurd roofing material that can be used for a dynamat alternative. I think its called weather gaurd or something like that. Huge roll for cheap.

 

listen to this man!!!!!!!!!!!!!!

 

id spend the money and get DYNAMAT, its very good. i loned my whole car with it, and whatta differ3ence it is

 

Are you hammering me, or those suckas who don't take note of my warning?

I really wish somebody would have warned me...I heard/read a lot of people saying the 'cheap alternative to sound deadening'....hahahaha...boy does it suck now! to me.

 

Hmmm...never really thought of it that way...I've always used undercoating to do the bottoms of cars and panels...and the 3M stuff does dry completely...trust me, I know.

Most any asphault based mass loader (like dynamat original) will give off some kind of funk on the first day of summer, and the smell is there a few days after you have installed it.

 

I'm still waiting to see how the expensive mass loaders somehow defy the laws of physics......

The Procon sheets at selectproducts.com are just mass loaders like dynamat...as you move down their product line, they do combinations of things....you can't compare those to regular mass loaders...that's apples and oranges.

Hmm...where do you get the 3M stuff? The stuff I got came from Pepboys...and it literally, never ever dries.

Maybe I can get the 3M stuff and spray it all over everything I've already done, hope it dries and in turn seals in the smell/stickiness of the Undercoating spray!

Sound like a plan?

 

I bought mine at a body shop, but 3M does have an online store. I really don't know how much this will do to help you out...I've never used undercoating on my interior panels, just mats.
