I have the same problem. Pole light is so bright it not only trespasses across his property line but reflects into the channel giving off a glare all night long that we have to endure. (If you didn't do this, did you try something else?) **Q: Hi can you use a heat gun on it to make a Mylar mirror for a dance studio ?** A: No idea but based on the product I would think a heat gun would melt the film **Q: Would this be sturdy enough to mount to a wood frame for removable reflective panels? (Grow Table project)** A: Yes **Q: Can this be used for wrapping paper?** A: I mean, yeah. It would make sufficient wrapping paper, but its primary function is for reflecting light or stamping out those balloons.
