Covering approximately 20 square feet per can, this product offers substantial coverage for typical automotive soundproofing needs. It also helps improve vehicle longevity by sealing out moisture and reducing vibrations that can lead to wear and tear. The 18 oz aerosol container provides a quick, clean, and straightforward application process, making it ideal for DIY enthusiasts and professional installers alike.
