I used to use the PET frozen pie crusts until the store replaced them with their brand...which were terrible. I use the Pillsbury refrigerated ones now. They do have to be at room temp to unroll properly. If they don't, I just finger press the holes together. I do brush melted butter the bottom of my ceramic pie dish and never have a problem with sticking. I also brush melted butter on the inside of the pie crust as well. It helps make a crispy crust, not soggy.
