Apply the Dynamat panel surface with a Dynamat roller tool. Take the roller tool and work the Dynamat into all of the contours of the metal panel. Using a razor knife, poke holes in any air pockets that may have formed between the panel and the Dynamat. Work the air out with the roller tool. Eliminating air pockets will ensure lasting adhesion of the Dynamat to the panel, giving you maximum damping efficiency.
