DYNAMAT Hoodliner 11905 – Self-Adhesive Hood Sound Deadener (32\" x 54\" x 0.75\" Thick) – Made in USA

Overview

The DYNAMAT Hoodliner 11905 is a self-adhesive hood isolation upgrade designed for both modern cars and classic builds. It combines a dense "Sound Soaker" foam core with a reinforced aluminized skin, delivering a calmer interior feel while helping shield the hood’s surface from radiant heat. This combination aims to minimize intrusive engine noise while keeping the exterior finish looking sharp for longer.

Manufactured in the USA since 1989, Dynamat is a trusted name among enthusiasts and professionals alike. The hood liner measures 32 inches by 54 inches and is 3/4 inch thick, providing generous coverage for many hood silhouettes without adding excessive bulk.

How it works

• The Sound Soaker foam absorbs a broad range of engine sounds, helping to soften rattle and rumble inside the cabin.
• The 1 mm reinforced aluminized skin reflects up to 97% of radiant heat, adding a protective barrier for the hood paint finish.
• The layered construction also forms a water and oil barrier, contributing to durability in challenging engine bay conditions.

Who can benefit

Car enthusiasts working on hot rods, performance builds, or daily drivers may notice a calmer interior and a more consistent exterior look over time. Because results vary by vehicle, think of Hoodliner as a possible enhancement rather than a guaranteed outcome.

With a straightforward self-adhesive backing, installation is designed to be practical for home garages and professional shops alike. For best results, apply to clean, dry metal surfaces and press firmly to ensure a solid bond around bends and corners.

Key takeaways

• Quieter cabin through engine noise dampening
• Heat management to help protect hood paint and appearance
• Made in the USA with a long-standing track record
