I am attempting to vacuum form an ODST visor using a DIY vacuum forming box following the tutorial from N8TEBB (awesome tutorial btw if you see this). I am having a problem where my PETG sheet turns white and opaque. I'm 99% sure I'm using PETG, as I purchased it from this link, but the actual package didn't include a label so I can't guarantee it. Any advice on how to remedy this issue would be appreciated.
