Best cheap plastic for DIY whiteboard

plastic

I am planning to make my own DIY whiteboard, so I was thinking about the type of plastic I will use. I found out that PMMA and PC is way too expensive for my first DIY whiteboard, so I am considering trying ou it with PP, PVC, PS or PETG first. Which of these would you choose? Will it be dry erasable?
Thanks very much.

I have gone through many different versions of whiteboards; purchased and DIY. Quickly, they all become terrible and the ink is difficult to erase. I tried car wax to condition the plastic as well with little results. I ended up stumbling upon a fantastic solution: I cam across some pieces of glass with rounded edges that were used for a shelving project. There were about 2'x3' each. Mounting these on the walls in our office was easy using some stylish brushed nickel mirror hangers. They work amazing and I highly recommend seeking out glass as an alternative.
