nice argument, but just doesn't hold up ... Mylar IS much more reflective than foil (and, the 'transparency' of it doesn't matter, as it is normally placed upon a wall, or sheet of plywood, etc.) ... and I know this, by measuring the reflected light with my light meter (hand-held photographers spot-meter) ... flat white is second place behind Mylar, foil is WAY down the list ... :smokin:

Apparently foil can create hot spots. But here's the thing, so can mylar. In fact, it's often used precisely because of its ability to reflect heat! Anyway, I've heard all sorts of misinformation, like that aluminum foil is only 40% reflective whereas mylar is 98% reflective. So I looked up some data in my thermodynamics textbook from college.
