Prepare Your Car

If you can’t remove the parts, bringing your vehicle to the car wash is recommended. They will assist you with the heavy work. The purpose of clip remover is to dismantle door trimming, and you don’t want to damage anything with the clip.

Degrease the surface before applying the first layer of the soundproofing mat

Using a roller, ensure that it is flattened firmly, leaving no air gaps or bubbles. You will see if you pressed down correctly when the grooves on the surface are smoothened.

Add another layer of sound insulation layer for more effective soundproofing. This time, place the thicker mat on top of the first, ensuring the first layer is also cleaned.
