Design Engineering Cool-Tape | Self-Adhesive Aluminum Heat Reflective Tape | ...

This stuff works really well. Just make sure your surface is cleaned and prepped really well. You won’t have any issues

I have used their products infrequently, but always with success. If I have any projects requiring thermal management, DEI is at the top of the list. This heat reflective tape seems solid (as much as it can for tape) and adheres well. It is easy to cut, though peeling the backing can be tricky. Fingernails, when short, make peeling the backing frustrating.

This product is affordable and easy to use. I've used a ton of Design Engineering products on my vehicle.And they have all performed perfect.

I bought this to fix a small firewall hole created by Fluffy Tailed Tree Rats. Please people do not feed these adorable little rats if they live in your neighborhood. They will multiply and nest on your motor! They seem to love Toyota Tundra insulation and wiring. On to the review. I used a 3M 2420 Tape to seal up the spot then taped over that with this. Why? Because I do not believe this will adhere as well. The tape is semi-rigid so it's not terribly difficult to work with. I cut it with ordinary house scissors. I wish I could have purchase in a 3" width. It is supposed to deal with heat up to 2000 degrees f. I have not had any serious heat under the hood and it's only been a short time. So if this actually holds up over time then yes it's 5 star. For now it's 4 star because even at a buck a foot it's cheaper than buying a new firewall cover or the cost of most of the kits. I also used some across a tear in the hood insulation blanket. The silver color works fine for me (Some tape comes in Gold). It is what it is. Tape that is supposed to shield heat that is fairly easy to apply.

I have used this in proper situations and improper and it has worked regardless. Heck I used it to patch a hole in a tailpipe I am planning to replace and it is working to stop the exhaust leak surprisingly. I also use it for temporary placement of electrical components that produce heat like resistors while I test them if I need to keep them away from stuff that can melt. Also have used this in a heat wrap around an air intake tube before.

I used this heat-resistant 1.5"-wide tape to finish off the raw edges of the Insulation Pad I installed on my 2005 Dodge Dakota. The 4'X5' roll was more than ample to replace the old, warn, and shredded OE insulation pad.The tape is highly sticky; I have no doubts, even though it's in the heat, under the hood, it'll last for the rest of MY life, and at least that of my Dakota! Very sticky, so care in application is required, but, it's fairly manageable, if it must be re-positioned!It's a great buy, and really, really does the job right!!

Looks okay- still in package due to project finished before arrival- a week late and no idea what happened??- did give me a $ gift due to hassle -Lost in Texas😮

I added a spice rack to a blank wall in my kitchen, thus creating space. However, that spice rack was reasonably close to a toaster; see picture. Enter this tape as a solution to deflecting the heat from the spices on the lowest rack. As you can see in the picture, the tape fit in two rows across the bottom of the spice rack (note: I didn't put the tape on first, which would have been a better way to go about it!), but it hasn't fallen off, and I have had no problems with the spices getting "cooked" prematurely.
