When bonding something that has a flange onto an exterior surface (I have aluminum siding) and the flange is held in compression to the siding, I like to use self-stick weather stripping, followed by a sealant around the edge of the flange. Should I have to remove the accessory, later, it is relatively easy to do. The weather stripping makes a good seal and I've never had it fail when held under compression.
What brand of material do you prefer for sealant, that is soft, pliable, and not permanent like silicone sealer for sinks and such. It needs to be removable with a reasonable amount of effort in the future, the plastic does not last indefinitely.
Since the flapper is usually under a hood, any type of caulk could be used. If you don't have a hood, you want something to seal from the elements. I use Geocel tripolymer sealers. It will harden but can be cut with a utility knife.
FWIW, I found the original plastic flapper in pieces. I made a new one , using aluminum sheet goods.
