Here is a description from a website selling it:
LizardSkin Sound Control (SC) is a high-tech coating that stops the vibration of sound waves coming from a surface before they enter the air. LizardSkin Sound Control can be used with LizardSkin Ceramic Insulation; when used together, LizardSkin Sound Control must be applied first. Typical applications include firewalls, floor pans, transmission tunnels, doors, hoods, trunk lids, under headliners, inside fenders, panel van walls, and other areas that generate vibration and noise.
For maximum acoustic performance, coat the entire interior surface and the floor, inside and out. LizardSkin is completely water soluble, meaning it offers an easy cleanup with just soap and water. 1 gallon can cover 20-23 square feet at 0.040” (40 mils) thickness.
