DUMPING STICKER

Vibration Absorption Layer: Heavy, viscous butyl polymer layer cover shifts panel resonance frequencies down to eliminate hollow sheet-metal ringing.
Thermal Radiant Foil Shield: Topped with a rugged protective aluminum foil sheet that reflects cabin radiant heat and guards the butyl core.
Self-Adhesive Peel Setup: Super-sticky chemical backing grips bare or primed car metals tightly without requiring any messy spray glues.
Acoustic Bass Enhancement: By turning your metal door frame into a solid speaker enclosure, it noticeably clarifies mid-bass woofer kicks.
