STP Legend 3 Vibration-damping sound-insulating material in butyl and aluminum 3 mm

STP Legend 3 is a vibration-damping material designed to reduce vibrations and resonances of metal surfaces, improving the acoustic comfort of the vehicle.
Composed of a high-density butyl layer and a reinforced aluminum foil, it represents an effective solution for intermediate-level soundproofing treatments, suitable for both car audio and general use. Thanks to its 3 mm thickness, it offers a good balance between damping performance and ease of installation.


How it works and what it's for

Sheet metal vibrations are one of the main causes of noise inside the cabin.
STP Legend 3 acts directly on the structure:

  • dampens sheet metal vibrations
  • reduces resonances
  • limits the propagation of structural noise
  • improves the acoustic response of the audio system

This translates to:

  • quieter cabin, reduction of metallic noises
  • more controlled and defined bass
  • greater surface rigidity


When to use it and where to apply it

Main applications:

  • car doors
  • floor pan
  • trunk
  • wheel arches
  • metal panels

It is suitable for:

  • general vehicle soundproofing
  • car audio system improvement
  • structural vibration reduction

Can be applied to:

  • sheet metal
  • metal surfaces
  • rigid panels

How many sheets you need and how to apply it

The number of sheets depends on the surface to be treated and the desired level of intervention. Installation:

  1. clean the surface of dust and grease
  2. cut the material to size
  3. remove the adhesive film
  4. apply to the surface
  5. press with a roller to ensure complete adhesion

For best results:

  • cover the areas most subject to vibration
  • avoid air bubbles
  • use a roller to improve adhesion

STP Legend 3 is a vibration-damping material designed to effectively reduce vibrations and structural noises, offering a good compromise between performance and ease of use. It is a solution for those who want to improve the soundproofing of their vehicle and achieve a more controlled and defined result, especially in car audio.
