Where can I find white plastic sheeting?
Black or clear will not work, and that's all I can seem to come up with on google. White and black on opposite sides could work, but I can't find the size I need. Speaking of size, I need it to be 16 to 20 feet wide (and similar length, but rolls could be longer); most seem to be 100' for sizes that wide. One other requirement- reinforced sheeting will not work, I will need it to have a smooth surface when I'm done. Thickness matters less, but obviously the thicker the more expensive and I think 4 mL would work fine. What's it for you ask? Sorry, but it's a secret, at least for now.
