Review on 🔥 Design Engineering 050506 Floor & Tunnel Shield II - Heat & Sound Insulation (42"x24") - Non-Adhesive for Maximum Performance by Mark Gancio

I bought this to replace the factory tunnel seal on my BMW E36 M3. The factory ones are notorious for falling off with age and the bell studs were extremely difficult to get to so I ripped off the factory ones and installed these. To cover the entire tunnel I made three pieces: two halves going from the engine to the back of the car and a smaller piece to cover the top where the top of the bell would go. I made sure to clean the tunnel with mineral spirits, then taped a soft and light sheet of rubber and non-permanent double sided tape all over the tunnel, I was able to take three templates, then measured and measured again to make sure I knew which side was which Adhesive backing was and which side will be open to the outside. After the three pieces were glued, I put three rivets on each side, right at the top, in case the glue came loose in the future. When drilling holes for rivets, you just need to make sure that there is nothing, wires or other important things on the other side. Overall I'm very happy with the results and think this is a better solution than the factory insulation on my car. came with. All that was left to do was apply gray high-temp RTV to the cut edges to keep moisture away from the fiberglass.
