Q: Is it necessary to cover 100 percent of an area to reduce noise?

  • A: To make any noticeable difference in noise reduction, a minimum of 30 percent coverage will be needed. Full coverage of any given area will always give the best performance.

Q: What should be used to clean an area before installing Dynamat?

  • A: We recommend non-petroleum based cleaners (Windex, 409) and/or isopropyl alcohol. For heavier soiled areas and to remove grease/oil, use a biodegradable degreaser. Lacquer thinner or acetone can also be used.

  • A: When properly installed, Dynamat Xtreme or Superlite will not run, drip, smell, melt, or come loose. Both products will tolerate temperatures of + 300 degrees F.

Q: On what surface will the Dynamat stick better?

  • A: Dynamat will stick best to a smooth, clean surface.

Q: Will Xtreme/Superlite stick to under coatings or spray on bed liners?

  • A: No. These products contain chemicals and rough textures that will not allow Xtreme or Superlite to bond.

Q: Do I need to tape the seams of Dynamat with the Dynatape?

  • A: Taping the seams is optional. Taping the seams will give a finished look, and will also keep any butyl /adhesive off your cloths and carpets when working inside the vehicle.

Q: What is the best product for reducing heat?

  • A: Our Dynaliner foam works best to reduce heat. Dynaliner (1/2 inch) will block up to 75% of radiant heat when used with Xtreme.

Q: Can the Dynaliner be used on its own without Xtreme to control heat?

  • A: Yes. Dynaliner will still effectively reduce heat. However, it is more effective when coupled with the Xtreme.

Q: Are there any other uses for Hoodliner besides under the hood of a car/truck?

  • A: Hoodliner can be used in many applications such as on RV dog houses and generator compartments, Boat and jet ski engine covers, UTV/side by sides, and any engine/motor compartment that needs sound and heat reduction.

Q: I have a noisy aftermarket exhaust. What is the best choice of products to help reduce this?

  • A: First, treat the cargo area and interior floor with Xtreme. (You may also need to treat the doors/rear hatch if applicable with Xtreme). Over the Xtreme, use DynaPad. Xtreme will damp the vibrations/resonations in the sheet metal. The DynaPad will reduce the lower frequency, airborne noise.

Q: How much noise reduction can I expect using Dynamat?

  • A: This will depend greatly on how many areas are treated and how much coverage is done. For example, treating all the doors (and rear hatch for SUV’S) can reduce noise by 3-6 db. This would translate to about a 25-30% reduction in noise. Full coverage of a vehicle that has no other sound reduction materials can reduce noise 9, 12 or as much as 18db.

Q: If I cover the large openings on my doors as per the directions, what do I do if I ever need to access the inside of the doors?

  • A: Just simply use a utility knife to cut the Dynamat to gain access to the inside of the door large enough to work through. When finished, use a small amount of Xtreme to reseal the opening.
