Installation Instructions

  • Remove your tires and any liners or plastic covering
  • Scuff metal or apply a primer if surface is waxy or shiny
  • If spraying Spectrum, cover your brake and suspension system with plastic wrap
  • Add Spectrum™ to the metal wheel well in 1mm layers to a total thickness of 3mm (3 coats)
    • If applying multiple layers of Spectrum™, wait 30-60 minutes for the product to cure and change color from blue to black
    • The temperature must be above 50°F for the entire 24 hours cure period after applying Spectrum™. Dry times increase with low temperatures and high humidity. If you expect longer than usual dry times, we recommend thinner layers (0.5mm instead of 1mm) to the same total thickness
    • Clean up with water within 30 minutes of application. Do not wait longer or Spectrum™ will dry. Always clean the spray gun between coats by running water through it.
    • We do not recommend applying to the plastic casing, fiberglass, or other obstructions.
  • Spectrum™ was designed as an soundproof undercoating. If you want to continue seeing reducing the noise levels further, coat the entire undercarriage!
