For those that have done sound deadening.

The MSDS for Quick Roof reads almost identical to Dynamats elsatomeric butyl.

This is from the Quick Roof MSDS

SECTION 5 - HEALTH HAZARD DATA
Primary Route of Entry:
Inhalation, skin
Health Hazards:
No data
Acute
Upper respiratory tract irritation. May cause nausea or dizziness.
Chronic
There are no studies to indicate that asphalt causes cancer in man. This petroleum based product contains a small amount of polyaromatic hydrocarbons which have been shown to cause cancer and respiratory damage in laboratory animals

Elastomeric Buytl MSDS is here MSDS – EnergyGuard Butyl Coating : LEXIS

If I avoided everything that might have harmed a lab rat I would not be able to leave the house.

I deal with chemicals and the associated MSDS info on a daily basis and this sounds like a fairly harmless product. The quick roof has a heath rating of 1 where the elastomeric buytl product is a 2 . Almost no product has a health rating lower than 1 even water vapor rates a 1. Read your cold medication bottle sometime if you want to get frightened.

I am aware of hundreds of people who have installed this in their vehicles without any problems other than some complaints about smell with some brands of sealant. Acoustically it seems to perform about the same as the original Dyanamat but not as good as the Extreme, the majority of the benefit comes from stopping the metal from vibrating and almost anything you attach to the large expanses of unsupported metal is going to work with heavier, thicker material having the advantage over lighter thinner stuff. Dynamat is good stuff I just do not think it is worth the cost and from a heath stand point I see little difference between the two. As far as durability none of my stuff has come loose let alone fallen off in three years since I installed it and I do not think the inside of my door panel is going to be a more hostile environment than the roof of a building, but that may just be me.


I understand some people have alot of money invested in dynamat and they will never be comfortable with the possibility that there may be a much cheeper alternative, heck I feel the same about my metaltech sliders.

That said if you find this product too scary by all means do not use it! Just be aware that some automotive products are also tar based like Fat Mat and most factory spray on stuff.

Is this from personal experience? My cruiser has been in eastern washington desert every summer since I put this stuff in and neither has it fallen off nor has it turned into a sticky mess, looks just as it did when I installed it and when I needed to do some body work recently carfull use of a heat gun was all it took to remove it.

Yes, I have seen what it looks like if it fails.

Asphalt gets brittle over time which means it may not fail the first few years.

The MSDS for Quick Roof reads almost identical to Dynamats elsatomeric butyl.

There's a big difference between the two. Butyl doesn't fume like asphalt does, and it has a higher melting point, meaning it's better designed for higher temp applications.

As far as durability none of my stuff has come loose let alone fallen off in three years since I installed it and I do not think the inside of my door panel is going to be a more hostile environment than the roof of a building, but that may just be me.

On a hot day (100+) at the hottest point of the day measure the temp of your roof. It will be 10-20 degrees higher than ambient...IF the roof/attic is setup properly, improperly setup roofs can nearly reach the same temps as the interior of vehicles...and will also prematurely fail, requiring reroofing every few years.

Go and measure the temps in your vehicle (left in the sun, windows up, etc). They will be much higher than on the roof.

I wouldn't recommend any asphalt based product. The cheaper sound dampening products are just as likely to cause issues and fail.
