Any tips on how to bend or form thin styrene sheet? I tried holding a piece over the gas burner on our stove, draping it over a metal ruller, hoping it would droop, which is what I want. But that puppy got too hot and nearly melted! What I want is a slight distortion--to replicate bent sheetmetal roofing, which I'm applying to my old-time gas station. BTW, the styrene is .010, which is nearly like paper.
