Design Engineering 050503 Floor & Tunnel Shield II 42" x 48" Adhesive Heat and Sound Insulation (14 sq. ft.)

Proper aluminum hear wrapping with asbestos lining and glue surface. Highly recommend it.

Received it on time through the international prime free delivery thanks for the great service, still need to install it on the car but I know from different channels that is the best cure for the gear box heat insulation, should work well

Good quality. Easy to use. Can mold into intricate shapes to heat shield my ecu and battery.

Very good quality good stuff

cut with either a really sharp knife... and good tin snips sort of fits anywhere, seems to stick well. 1/4 of kevlar padding seems perfect !!

This practically holds itself in place. seems to work great.

I will re-edit this when I've put some heat to it and seen the miles it holds up to. As far as the product itself though, initial impressions are very good. I had the engine and transmission out of my miata so I could hopefully do this job the right way. There is a video out there of a gentleman putting one of these in with it installed and I can't imagine it would hold up as well. Reasons are numerous but I think the most important being there's no way you could get the tunnel clean enough for proper adhesion. Yes this product is extremely sticky, but like anything adhesive once you clog that surface up with contaminants it's going to lift off the surface and not provide the kind of bond intended. If you've come here, your car is too hot due to tunnel heat most likely. Though I suppose this product would work for lots of places. The aluminum side of this shield resembles the sort of thing I've seen on lots of new oem shields. It's got a cratered surface, it's somewhat reflective in nature. It is fairly stiff as a result, though it bends fairly easily. My application is for a race car (miata) and I've always found the tunnel gets just too hot from exhaust especially during the summer months (I usually don't have carpet either). So hopefully this helps this season. I've attached an image that shows how mine went in. I made sure to thoroughly clean the surface before-hand and started with the driver's side. Working it down and peeling back the adhesive protection layer of the product I was able to get it to finally adhere the way I wanted. Note, I cut my product with tin snips at the folds of the body to help ensure I didn't have any bubbles in where it applied. I don't believe there is any real way to not do this at least on a miata's tunnel. We'll see how well it works but I'm real hopeful it solves or at least helps to mitigate the heat issue. Hoping cutting it the way I did doesn't somehow ruin it's overall effectiveness or make it less long-lived. Will update with how it holds up. [...]
