Can we talk about sound deadening products?

[jy211]

I used second skin and dynamat in my '55. All I really hear is the exhaust!

Weight is an issue for me so I live with the sound

I have heard good things about lizard skin but am concerned
that it may trap moisture and cause rusting.... Detomaso
used a lot of spray on sound deadening for the underside
of the car and in the engine bay which caused a lot of rusting

The Mangusta put it on the inside of the doors and I have
heard many with rusting there as it in trapped moisture

These were products of the 1970's.... maybe the new ones
work a lot better.. anyone else had any experience?

I've used Dynamat, Dynamat Lite and Raamat

I have used Lizard skin on three of my builds and I think I'm done with it. I don't think it works well at all for sound and the heat product hasn't made my jeans tight. I always use Fat Mat on the inside of the car in conjunction and I think it's doing 90% of the heat/sound dance. I know it's about 30% thinner than DynaMat, but you don't need to pave a car to take the tinny sound out. I just bought 80 square feet on ebay for $100 shipped and have used it on 5 cars. It works great.

I recently used 80mm Fat Mat and thought it did a great job and was a lot cheaper than Dynomat and got it shipped via Amazon prime in two days:

We started using Boom Mat about 3 years ago and have been very impressed. It is one of the very very few products that is a standard on every car that we build. We have used many other brands in the past and like the Boom Mat the best. They have multiple thicknesses on the sound dampening mat and a great collection of other heat and acoustic handling materials.

To broaden the scope of this topic a bit, is it unwise to apply Dynamat (or any of these products) on vertical panels?

Years ago when applying Dynamat to my Camaro I was told it is risky to do the doors. That the product would not hold and would "slide" downward. Is this true? I am doing a Chevelle soon and would like to know. Also, I noticed Malitude has Dynamat inside the doors.

Curious has anyone put a mat product over lizard skin? Curious how that might work I have both the ceramic temp product and the sound deadening from Lizard skin on my car. I have been thinking about adding some dynamat to the inner firewall and inside of roof on top of the lizard skin

I've used Lizard sound then ceramic on the bottom of the car. Then used FatMat on the inside of the cabin. Seems to work well.
