Oh really, how do I know you didn't peal the aluminum backing off of your mat deadener and spread a layer of fiberglass on and put the backing on top of it LOL hahahahaha.

If it has fiberglass or cement or something that becomes rock hard it should be illegal. But that elemental designs blue paste is really thin and is not very strong. But I don't think it has glass in it so it should be legal.

I didnt I put the fiberglass on the outer side...

I am interested in a product from Second Skin call Spectrum Firewall. Does anyone have any info on this product, or have they used it before? It is a spray. More info can be found at www.SecondSkinAudio.com I have emailed the juding staff and they requested samples. I do not have samples to provide as I will not purchase it until I get a ruling. [Confused]

Then you have to ask the distributor for an sample to send to Steven Benton.

We, the judges can't contact every manufactor for that info, and if the manufactor is NOT sending us a sample and get it approved its illegal for dB Drag Racing use.

Thank you Tor. I requested a sample be sent to Steve already from the manufacturer. You must understand that this step is new to dampening manufacturers. Second Skin has absolutely no intention on making an illegal product. Their intention is to make the absolute best dampening for the intended application. He knew nothing of the new ruling for dampening and I'm sure he may be a bit frustrated that each new product has to be submitted for testing. I think that you may get the same reaction from other dampening companies as well. I understand this step, but it may take a while for other companies to agree with it and understand as well. Basically what you are telling manufacturers is, if you want your product used in the lanes, it must fall within the bounds of the DBDRA ruling. So in turn, companies will either do their best to be within the legal DBDRA guidelines, or they will just turn their back on sponsorships with audio competitors.

I understand this, and I understand your concern, however, we think its best to do it this way, and most fair.

We would't have this problem if competitors and manufactors didn't "push the limits" of the basic rules.

What he is asking, is a material legal if it is more than 2 mm thick before it's installed, but after installation of 2 layers, it is under 4 mm total size. This could be accomplished with a mat type material by rolling it and compressing the inner structure.

The only thing is, I can't be positive that the whole panel is under the limit.

The only advantage of a mat is that it was supposed to be easy to make sure that a car is legal by counting the layers. This product could very well be thicker then the rules allow at points in the car, while appearing legal.

Working on it
In the world of bridge painting we use a digital mill thickness guage (1 mill = 1000t/h of an inch) super easy to use also.

Magic Mate is ticker before its applied, so no problem... But MAKE SURE that its under 4mm after installation.

I have Magic Mate in the shop, which I believe is 3mm. I will check in the morning.
