The factory is not going to have a recommendation for "rust repair" that involves introducing some extra metal of any kind.
The factory repair recommendation is going to be to replace the rusted body panel with a new, factory-produced piece.
The rulebook says:
"All chassis/structural/electrical repair, if performed, shall be
in concurrence with factory procedures, specifications, and
dimensions. Unless specifically authorized by the manufacturer
for repair or allowed by these rules, no reinforcement, i.e.,
seam welding, material addition, etc., is permitted."
So if your shop manual or other manufacturer documentation doesn't explain how to add metal to repair rust, then, sorry, you cannot add material, period. Seems cut-and-dried to me.
