Is Adding Car Soundproofing Cotton Effective?

[VanAmir]

Adding car soundproofing cotton is effective. The functions of soundproofing cotton include: noise reduction, flame retardancy, reducing body vibration, waterproofing, rust prevention, and thermal insulation. The locations for full-vehicle soundproofing include: chassis, four doors, trunk, tailgate, engine hood, fenders, roof, dashboard, firewall, and U-shaped groove. The method for full-vehicle soundproofing is as follows: 1. Drive the car to a safe location, engage the handbrake, and turn off the engine to ensure safety. Remove the interior trim in the order of outside first and then inside, exposing the working surface, and place the removed screws and clips into sealed plastic bags. 2. Thoroughly clean the working surface with asphalt cleaner. For stubborn residues, try using other specialized solvents to dissolve them first, then slowly scrape them off with a specialized scraper. 3. Reinstall the interior trim from inside to outside as originally positioned. During installation, ensure all components are reinstalled exactly as they were, and all screws and clips are tightened and secured to avoid secondary noise.
