Hey man the shop I work at has used some of the lizzard skin before and it seems to work pretty good. It does a good job on the insulation part but I am not so sure about the noise vibration yet as we have not driven the car yet. I like the dyna-mat or hushmat for that. We still use old fashioned foil back insulation under the carpet to cut down on any heat that can get in. The shop that I work at sells the Hushmat and Dyna-mat let me know if you need any more info.

I started reading that post and it is really good. I sell this stuff at my shop and it is really interesting to know that we could make it ourselves for the cars that we build and save a lot of coin. If anyone here tries this I would love to here about their results.

I'm gonna mix some up for a car thats getting floorpans. Gonna be
a while though. I'll post pic's and tell how it works out.

Quote,

Efforts and some results

Effort: I purchased 2 one gallon bags of micro balloons fro Wicks Aircraft Supply at a cost of $13 with out shipping. Mixed one bag into a little over a quart of white Glidden semi gloss left over latex paint. This is dusty stuff so I wore a chemical mask and eye protection. I mixed the whole works by hand and got about 7/8ths gallon of material. Mixture was about as thick as thick pancake batter. I applied this mixture to the inside firewall and cowl of my 53 F-100 using a 2.5 inch nylon brush. I also applied the material the inside back wall of the cab below the rear window. I applied 3 coats to the firewall/cowl area and 2 coats to the rear cab wall. I tried to apply these coats as thick as possible allowing an hour between coats. My goal was to have the dried material as thick as a credit card. I estimate the total area covered to be about 30 sq ft and I used about 2/3s of my material. I then allowed 2 days for the material to set.

Some results and observations: There was no gloss to the dried material and it will scratch with a sharp object. I don’t think I would use it on the outside of the cab. I don’t know if it felt like petting a lizard not having an occasion to do so; however it looked like flat wall paint and definitely had more texture. We had a warm sunny day here in South Texas before Christmas, around 80 degrees, and I rolled the cab into the sun with the outside of the firewall facing the sun. After a half hour or so the outside of the firewall became hot enough that it was not comfortable leaving my hand on the outside metal. The outside of the firewall is painted with two coats of epoxy primer. Inside the firewall I could place my hand anywhere without any discomfort. It was warm but definitely not hot. I do not have a point and shoot thermometer but my Craftsman 82400 multi meter has a temperature probe which I used on both sides of the firewall. I recorded a temperature of 124 F on the outside of the firewall and 102 F on the inside at the same place. The inside back wall of the cab was also in the sun and remained cool to the touch. It did not seem to absorb any more heat than the ambient temperature. Both sides of the rear cab wall felt about the same.

I have now mixed my second batch. I bought a quart of exterior latex paint from Lowe’s mistake shelf for $1. The color was an off white a little on the beige side. This mixture came out as very dry peanut butter. Dryer than the kind you have to mix before eating. I was able to roll this mixture on the inside roof after the addition of about a pint of left over white ceiling paint. I had applied 2 coats of the remainder of the first mixture to the inside roof so that made the 3rd coat. I will add one more coat to the roof and then use the rest of the mixture on the floor. I still plan to use my Quiet Ride kit inside the cab but I believe the latex micro balloon coating to be a definite bonus. One further observation: the hollow, ringing sound when the cab wall was thumped is now changed to a dull thunk, definitely less vibration. All in all for the price and the effort, I am pleased.
