I use a mixture of 2/3 cup of salad oil and 1/3cup liquid lecithin, shake it up and brush on both sides of the screen. This mixture is essentially Pam. A lot less wasteful, as there is no overspray.
I stretch the dough to the approximate size put it on the screen and stretch to final size. Put on toppings.
Never have a problem. Got this out of a bread book about 25 years ago. Use the mixture in bread pans, cookie sheets or any other pan for pizza.
