grill restoration

I have a few little broken pieces on my grill, any ideas on a good technique to repair them? Do you just glue back together and if so regular filler?
Describe the parts broken. If it is the mounting tabs, just gluing will probably be too weak. I repaired some broken tabs by adding some spring wire as reinforcement with Epoxy Steel Putty to bond it all together. That seems to be working OK. I even used that to make a completely missing tab.
