Reflective Material

Just a quick question, has anybody used silver tarp as relective material for their setups

I never have but I'm pretty sure that mylar is cheaper.

Mylar is a bit cheaper - I'm sure a tarp would work to a degree though.

If you know someone that works at a convience store or at a food service place you can get pieces of mylar for FREE. The boxes that they recieve the soda syrups in contain app. 3x3 or 4x4 sheet of mylar on the inside and they ofcourse, just throw the boxes in the trash.
