Friends, I am attempting to permanently bend some .030" styrene sheet to form a radial car roof. I want the permanent bend not only to avoid any unrelieved stresses, but also to be able to remove the roof on occasion. I have never done this before, and so far I have had no progress (using hot water poured over the sheet tied around a drinking glass, etc.).

How have others done this, and if so, how?
