I am at the same cross road as you. I contacted Lizard Skin, enclosed is the response I got from them, maybe there is some value in it for you. As a side note I have used POR 15 on the Rustang, pretty much everywhere. I have had nothing but positive results. It's the only paint that I have ever used that stays on my skin for a week.
To Lizard Skin:
Is Lizard skin a proper product for undercoating to seal the underside of a car. I am currently working on a 1966 mustang that is going through a full body rebuild with new floor pan, rear quarters, trunk pan, door skins and am thinking of using the Lizard Skin product for this. Is this an appropriate use of the product. The thermal and noise attenuation are not really a concern to me.

Doug,
Thanks for your interest in LizardSkin.
We do have two products that will quiet, cool and protect your ride, they do completely different Jobs. I know you mentioned heat and noise is not a concern you will be surprised how much noise and heat these cars draw. When we look at both products and what they do think about some goals for the vehicle and what you want to achieve, you will know it each time you drive the car because those annoying rattles, vibrations, the hollow echo noises are gone and the car will feel 30 to 40° cooler on a nice hot summer day. Floorpan temps greatly reduced.
As a spray-on insulating coating used on many applications were heat is an issue. LizardSkin Ceramic Insulation is the ideal way to stabilize thermal transfer. Unlike more complex insulation options that are pieced together, the coating is a one-part, spray-applied system. Easily applied to irregular surfaces and tight spaces, its water-based formula contains a mix of durable acrylic binders and air-filled insulating/reflective capsules that cure quickly, insulate effectively and minimize downtime from the application.
The coating adheres to most any substrate without the need for a primer with the exception of ferrous substrates and is extremely lightweight. It keeps temperatures more comfortable and stable at minimum thickness (0.5–2.0 mm). LizardSkin Ceramic Insulation is an ideal insulator for a variety of applications example Auto restorations, RVs, ATVs, military transport, emergency vehicles, tractor-trailers, HVAC, Livestock trailers and all other large vehicles and on any substrate were heat is an issue. Applied as a seamless membrane in two or more layers, the coating is non-combustible,
environmentally friendly, No Toxins and easily cleaned with soap and water.
LizardSkin Sound Control (SC) is a spray-applied automotive sound damping coating that is great for reducing exterior noises. It is an advanced, water-based composition of a high-grade acrylic binder with sound-damping particles. It is used by custom car, street rod, truck builders and anyone else who wants to reduce unwanted noise. Being a spray on application it can cover all areas of the Vehicle any uneven surfaces and support structures the more surface you cover the better the performance. It can also be applied to the exterior floorpan being a seamless application it creates a constant moisture barrier and works like an undercoating.
We have learned the more of the substrate that is encapsulated the better the performance. Here’s what we recommend that will give you the best performance out of these products.
Starting with the Sound Control encapsulate the entire interior example firewall, floorpan, ceiling, inside door skins, quarter panels and under the door panels. As an option you can apply to several exterior areas floorpan, firewall, wheel wells (protects from rock staring) and under the hood (CI only). Next we apply the Ceramic Insulation for maximum thermal performance stack the “CI” right on top of the “SC” in the interior firewall, floorpan, ceiling, inside door skins, quarter panels and under the door panels it’s in all the same places the “SC” was applied.
The secondary benefit to these products these products are applied to form a seamless membrane that is a complete moisture barrier so they work just like an undercoated sealing and protecting the exterior substrate. Please let us know if you have any further questions.
