Step 3: Apply the Material
Apply the Dynamat to the mounting surface with a Dynamat roller
tool. Take the roller tool and work the Dynamat into all 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 ensures lasting adhesion to the panel to give maximum
damping effect.
