Beeveer 36 x 96 Inch Extra Large PET Sheets Roll, Transparent Clear Flexible Plastic Sheet for Craft, Picture Frames, Sign Blank, DIY Display Project, Protective Barriers

I used a thin clear plastic sheet with a somewhat rough surface. Honestly it wasnt very good, too rough. I'd recommend something smooth, probably something like this? https://www.amazon.com/Beeveer-Plexiglass-Transparent-Flexible-Protective/dp/B0FBWVFJXF?sr=8-20 Should also be pretty thin. You can alternatively search for 3rd party replacement surfaces, something like this https://www.ebay.com/itm/271169608750 Also the paint I used for the backside to make it black started peeling soon after, was the wrong kind of paint. Needs to be one that sticks to smooth surfaces well while also being flexible enough. Not sure what type of paint would be suited.
