Currently using it in my build...just put on one layer yesterday. Go to my "re"build log below...haven't put it up yet on the build log, but it will be tomorrow. You can see the pics of it on my facebook @ www.facebook.com/bakermaninc

Anyways, yeah, its just as good, when enough layers are applied. I like it better simply b/c its ALOT easier to work with!

Ive got it on my wire straps and i dont think it would be good enough for a sound deadener.might cover up a little road noise but nothing substantial

I agree with nate. I sprayed it on the entire floor of my 67' and it did help with a lot of road noise but i dunno about using it alone as a deadner.

The problem with Duplicolor's undercoating is that it's not an elastomeric polymer, it's a asphalt/bitumen/rubber mix. When dry it's too stiff to absorb and control vibrations. Basically it's just adding mass to the panel.

It is also asphalt based, not the best product to use for sound deadening.

It will work, just not the best option out there.

what would be another alternative to that thats around the same price?

How much is it? I think around here it's like $6-$8 for an aerosol can.

A few products that I would suggest looking at.

Second Skin Spectrum

Cascade Audio VB-1X

LizardSkin

All of these are sprayable and lightweight (once dried a gallon of most of this stuff is around 10 pounds).

I think price is going to be a bit more with any of the above options, but it will work better and weigh less than Duplicolor's undercoating.

how much of Second Skin Spectrum would it take to do a noticable differnce even if duplicolor would just reduce road noise thats kinda all im after just slight sound deadening from outside stuff and a slight increase sq.

Where are you planning on applying it? To the underside of the vehicle or interior (trunk, floor, etc.)?

And what is your overall goal? To improve SQ or to lower the overall interior noise level of the vehicle?

A gallon will cover a solid 20-30 sq. ft. of area at the appropriate thickness (2mm.) and is sufficient enough to cover:

1. Most trunks (excluding Town Cars and other large sedans).

or

2. Most floors.

or

3. Several doors.

So to answer your question, a gallon would give you enough to do most any area of your choosing AND for you to see (rather hear) a reduction in overall noise and improvement in SQ.
