This fucking stuff has been out two years.................
I remember posting about it like six months ago, suppose it takes a while for people to catch on ............
The stuff is less reflective than standard mylar and it isn't 100% heat resistant, there is still some technology that can see through it. That's the low down.

Its also more expensive than mylar and its identical, which means the potential for being ripped of = high. You could be just getting standard mylar.
