Thermal coating and Sound dampening

Lizard skin has become popular and recommended by vintage air for heat reduction and sound dampening, better than dynamat. I think this hytek stuff was the OG and probably is a superior product.

Only $13 per gallon for the ceramic microspheres, can add to any paint

I was recommended RC#233 (under acoustical coatings) for thermal/acoustic coating. It’s a water based acrylic paint mixed with the microspheres.

What do you all think?
 
I've used lizard skin for almost 10 years now and never had a problem so I won't experiment but someone might want to try and save money.

Heres my budget dynamat story. First heard of the stuff in the mid 90's. We had a local manufacture for the commercial dynamat that the OEM's used. Back then stereo shops were plentiful. The shops in the area all sold this stuff and it was cheap. Either employees stole it and sold it or was 2nds and blemishes? Well even at the discounted price it seemed to expensive for my cheap 20 year old butt could afford. I had a 91' 2 door gmc jimmy with the factory ground affects and cb radio. It was the bomb and I thought I was cool. I Wasn't. Some guy bought a piece of it to work and told me all about. He was a stereo punk. The theory sounded great to me.

I worked summers up to this point doing roofing. We used a product called ice and water guard that appeared to be the same stuff to a 20 year old dummy. It was asphalt based and sticky on one side. Perfect. A roll was under 80 bucks for enough to do lots of vehicles.

I gutted my jimmy and lined everything but the ceiling. Put the interior all back together and patted myself on the back for a great job. First hot day on the sun I opened the door and the asphalt smell rolled out of my beloved Jimmy. It would take your breath away so I had to regut the Jimmy and pull out my rolled roofing. Of course I spent 80 bucks so I just put the interior back together since I didn't have the funds to do it again.
I was dating my wife at the time and she will still bring this up occasionally if I'm being cheap. Great memory and lesson learned. I could write a book about the pitfalls of trying to save money and expecting results of a pro.

I have seen this home brew for years and is it the same stuff??
No way anyone knows the size of the microspheres and type they are using as well as the amount.
I use different microspheres and use three different ones for different reason and they are different mils and different material unlike what you buy at the art store.
 
Lizard Skin is good stuff. Need a schutz gun to spray it on but a word of caution, I got obsessed with making it all look even, lesson... don't hose on coats. Mine lifted in big bubbles across the firewall of my vette and I had to scrape it back down with a putty knife and start over. Worth about 25hrs. But spray it even and wait PLENTY time between coats and it will be fine. I couldn't get an even consistent finish to the surface btw... I felt defeated being I've been spraying paint most of my life. :rolleyes:

"Tripping over dollars to pick up dimes" in how my grandpa put it. It's a struggle.
 
What myth? There’s also the myth that a name brand is better than something with the same chemical properties. There’s plenty of people here that disparage POR15 and make good arguments against it. I’ve never used it and thanks to this site I don’t think I ever will. But in regards to hytech microspheres they seem to have a longer history in the market and I suspect some of their products are just as good as lizard skin. Mascoat, who makes lizard skin, has marketed their product better and have a catchier name but from what I’ve researched their product isn’t superior to hytech.

These arguments are like big pharmaceutical companies claiming their drug is better than the generic when the 20 year patent expires. The formulation and excipients are a little different but the active ingredient is the same. Sometimes a trade name is better but not always. It’s all about trying to protect their share of the market.

I think what you will find here as opposed to the big pharma argument is that these guys have actually run businesses and used the products. They are not paid to pass down their information, hell they might even lose some business to us DIY guys :) So you're getting info straight from the people who do this for a living, if you cannot trust that what can you trust? In addition Barry, who owns SPI replied, so again you're getting real info, not some keyboard warrior or Youtube star...
 
I definitely appreciate the dialogue. This post is regarding non-SPI products. Barry said he uses different microspheres for different purposes. Sounds like he has the knowledge and access to make his own thermal coating. The reason for posting was to discover if anyone had researched this stuff or added microspheres to SPI paint. As far as I know no one here is affiliated with or sells lizard skin so no need to defend it other than it seems like a good product so far.
 
well i knew the man who developed lizardskin here in texas . i started using it when it when he first started . your welcome to use what ever you like but until you have some years experience of using it your just guessing .
bob sold lizardskin years ago and i know nothing about who owns it now .

That's cool. I'm not an expert, just interested in the technology. If I get more in-depth info about hytech's microspheres, I'll let you guys know.

Jelco I wasn't discouraging using microspheres to make up your own mix and in fact I think Barry was saying he does just that (?correct me if I'm wrong), I was just relaying my mistake using the branded stuff so as to save someone else the same pain. That said, I did consider using the raw microspheres in a latex paint base but as I had a hundred hours in cleaning the bottom of this vette I just couldn't risk not getting it right considering the LS guys have a proven formula. If it was going on a farm truck or a dirt track car or similar I may try my own mix.
The LS is very thick in the can btw... mix it with an electric drill and mixing attachment.
 
jelco i didnt use the hy-tech stuff your looking at but i did try the sc1000 pre mix sound deadner they have about 5 years ago under my roof skin and on top of the inner roof panel. on my 60 chevy truck..when i replaced some rusty metal.. spayed on 2 coats with a schutz gun over spi epoxy... i can tell you it does dampen that tinny sound.quite a bit..cant compared it to LS havent used it .but its still well stuck in place (because of epoxy im sure) .cant tell you anything about thermal qualities yet it hasnt been in the sun. i do recommend anything water based should be sprayed over epoxy sealed metal..good luck.
