Old School...send me your address by PM and I will send you some of the teflon sheet that I have here in my little hands! This is good to about 400 degrees so should work fine for what you need it for, it is also 18 inches wide, I'll send you enough to hold you over for quite a few replacements and hope it works well for you. I'll look for a message from you tomorrow in case you don't get on again tonight. Mattie
