A lot of die cast have orange peal bad if you want the chrome around the windows to look right most hobby stores carry a thin chrome like tape you cut it and stick it on works great and looks real.I'm a old model car builder you need any idea on anything let me know.On the Lemans stripes Shelby used they get wider at the back of the car most die cast don't do this if you want to heres the specs on the real cars you'll have to scale it down
