The weather stripping will work. At least it is safe to use according to the detailed info.
From a practical standpoint, I belive that after you use it a couple of times it will become so gunked up that you will not want to use it. I believe that you will have sticking issues with it.
I use folded tin foil strips to drape over my drun in order to get a tight seal. I have to repace it with new foil on almost every cook. It just gets to sticky from the humidity.
