plastic sheet question

[Pim]

I have a heap of plastic sheet lying around and am wondering if I could use it for modeling purposes in place of styrene

Test it...see if it is compatible with the cement(s) and paint(s) you normally use. If it is not styrene, you may be able to use super glue to bond it to styrene. But if paint won't adhere, the plastic won't be of use to you.
