bathroom remodel

in the process of bath room demo and remodel, job is almost completed and am about to install a new toilet set
in looking at the floor connection where the waxring is seated and lower section of toilet is attached, it is rather badly rusted.
is there something I may do before I attach the new toilet set, since the drainline is now exposed and everything is clean and new? should I consider patching the ring/waxseal area with something like royal jelly? use an epoxy bond after sanding rust away? something else?

Depends on what you mean by badly rusted. If it is just the entire surface is rusted that is common and nothing needs to be done. If it is rusted through and crumbling then you need to replace the flange.

NOTE NOTE NOTE. Remember to take the rag out of the shithole before putting new toilet on! Murphy says rag will go way in to next elbow then jamb and block.
