The Dynamat DynaTape Aluminum Finishing Tape is a premium, high-adhesion utility tape engineered to complement your vehicle's sound deadening installation. While insulation mats handle the heavy structural damping, DynaTape serves as the essential finishing touch for wrapping up your project. It cleanly seals up exposed seams, covers raw edges, and ensures a clean, show-quality professional appearance across your entire cabin layout. Performance Engineering & Butyl Control 2-Mil Aluminum Shielding: Manufactured from a high-durability, 2-mil thick aluminum foil backing that provides excellent strength and radiant heat reflection. Butyl Migration Containment: Specifically designed to block and contain unwanted butyl migration along the raw, cut edges of your sound deadening mats. This prevents the sticky internal core of the mats from squeezing out over time and making contact with your premium carpet kit or upholstery. Integrated Wiring Attachment: Serves as a secure, high-temperature method to attach and route electrical wiring harnesses directly over your installed insulation sheets, preventing under-carpet cable rattles. Seamless Vapor & Moisture Seal: Tightly seals the joints and seams where individual sheets of Dynamat meet, forming a continuous barrier that blocks air, moisture, and road dust from sneaking through the gaps.

Once you lay the tape over a seam, press it down firmly using a solid rubber or wooden application roller tool to flatten out the edges and completely activate the pressure-sensitive adhesive.
