Review on 🔇 HOMCHEK 5mm Auto Heat Shield Sound & Dampening Insulation Mat - 21.53sqft - Noise Control, Waterproof, Self-Adhesive Foam - 40" x 80 by Frank Dubey

This is a very cheap product. It technically works at best as long as you don't touch the glue or if you don't care about a clean look. If you glue any part of it to something and think you can just remove the smallest part and glue it again, you are wrong. The foam will break down before your eyes and you can't remove it effectively, leaving a ton of small black chunks of foam that need to be rubbed vigorously with your fingers or scraped off with a flat razor blade. Would send back if I had any left to send back.
