Used a few sqft of this material, along with the equivalent from Streetwires (PartsExpress) and a ton of Peal 'n Seal (Lowe's) for the rest.
I would say that Peal 'n Seal was the easiest to apply, but also the thinnest (an cheapest). So if you are doing some serious job you may want to double or triple the layers.
The NVX material was the thicker of the three I used, and once it's glued it stays soft which is very good. But beware, you will never get it off again. The only thing I would reproach is that the aluminum is quite thick, which makes it hard sometimes to comply with shapes. But it is good to fill in big gaps or openings and add some rigidity.
My preferred material is the Streetwire stuff, which is a bit cheaper. It was thick enough and compliant enough to make it really easy to install and it sticks like crazy while being forgivable if you make a mistake.
