rust...
I used VACTAN on my trailer and campervan , comes highly recommended from camper forum , seems ok ,follow it with grey epoxy primer .
BTW ,the zinc-rich , weld-thru primer does not give a good adhesion to metal , only use it where you can`t get other stuff like vactan or etch primer on , post- welding .
