I think the weather in different parts of the country has a different effect on the plastic. I flip the molds, sprinkle them with salt, pour another round (usually 10 molds or so), scoop up the salted ones, take them in the house and my wife bags them and its done. I think once or twice I've had baits set up funny and get a bend in them and for what reason I don't know. If they are a straight color I just cook them again. I let them set over nite if I don't need right away.
