DADSSUB What about bed liner? Would it help with sound deadening?

DADSSUB Is the Lizard Skin mixture for sound reduction or temperature reduction?

Big_John Following up on my post, I did my deck lid on my Chrysler today.

I mixed the micro-balloons I got from Wicks with a quart of Rustoleam latex paint. The mixture was thick, but still pourable. I removed the deck lid and striped out the lock etc. and taped all the openings except one access hole near the latch and the two holes where the hinges go in.

I poured the mixture in the three holes, and after sealing them with more tape, I then left it standing on each of its sides for a few minutes. As it dried, I left it in each position a little longer, spending most of its time laying face down.

When I was done, I removed the tape and propped it up on saw horses face up and let it drip for a while. To my surprise, not a lot of paint dripped out.

Got it cleaned up and put it back on the car later. First thing I noticed was the trunk closed with a much less "tinny" sound. When you knock on the sheet metal, it almost sounds like knocking on fibreglass, rather than the steel panel.

So.... I'd say it worked. If I were to do it again, I would mix up more than a quart of paint, but that's the only thing I would do different.

hduff The top ten reasons are: COST.

Those insulating glass microspheres mentioned can be added to any paint.

DADSSUB Not that old of thread so I'm hoping people area still paying attention to it.

Was interested in finding out what the results were if you used some other paint instead of house latex. Our fab shop has a really nice primer they put on industrial duct work that I am planning on using inside my body.

I'm also a little confused why you would put the home made lizard skin over Dynamat? Don't they both do the same thing?

I'm thinking of using Latex just for ease of cleanup. I'm thinking this will make a mess.

DanTwoLakes I'm sure nobody has, but give it a try. What do you have to lose? At worst it doesn't work, but if it quiets the car down even a little, it will be worth it.

Big_John This is a great thread that actually brought me here to lurk several years ago. Time for me to ask a question....

Has anyone ever poured the home brew Lizard skin into a panel opening and then rotated/turned/spun the panel to cover the inside?

I have a 70 Chrysler 300 vert that I want to quiet down. This car has the most highway noise of any of the big Mopars I've owned over the years. A lot of it seems to come out of the trunk area. The quarters were replaced sometime in the car's early lifetime and the usual heavy factory applied undercoating on the inside of the quarters is missing. I'll apply the Lizard Skin there and on the trunk floor.

I think I'd like to coat the inside of the deck lid too... but there is only some openings around the latch and hinges. I'm thinking I can take the deck lid off and pour some of the paint mix in the holes and twist and turn the lid until it's covered inside.

Has anyone done this??

496CHEVY3100 I had some extra Dyna mat left over so I put some on my fuel cell corners since is is only about 6 in from my exaust,,not that I thought it would catch fire ,,but to help prevent vapor lock

don't know how it will stand up to the weather ,

Chopchop Thank you.

It's probably not the best stuff you could put a couple inches away from a turbocharger but it seems to hold up pretty well to the temperature!
09-11-2013 03:13 PM
496CHEVY3100 Souds like it should work fine for you ,,didn't think it would stand the heat,guess that proves me wrong,

That is one sharp truck.

Chopchop I've had the bubble wrap on the firewall for the last 5 years and I haven't had any problems with it. In fact, I had it 2 inches away from my turbocharger and it still didn't melt.

Instead of using latex paint to mix the microspheres with, I ended up using Rustoleum rust paint and I brushed it on the firewall.

The whole purpose of my wanting to use a home made concoction of Lizard Skin was to get away from using high dollar "real" Lizard Skin or high dollar Dynamat / Hushmat etc.. The foil bubble wrap is cheap and even if it is only a weeeee bit better than nothing, it might help a little bit and costs very little.

I don't care about sound deadening, I'm in this for heat control from the engine to the passenger compartment.

496CHEVY3100 That is what I was thinking also .the bubble wrap will probably melt and I would keep a fire extinguisher close by as latex paint is flammable as is the bubble wrap.

the fumes from hot latex could be toxic also ,,,I would check before putting it under hood next to extreme heat. Just saying

DanTwoLakes The Dynamat would probably be enough, but he could cover the Dynamat with the Lizard Skin in any color he wanted and it would look better. The reason I said Dynamat was that it would adhere to the smooth, clean metal extremely well, and he was going to use foil faced bubble wrap. The Dynamat would just be a lot better choice than the bubble wrap.
