Mine ? No rust anywhere in or on the tub, so I'll keep using it.
The racks which hold the ceramics need replacing this year. They are totally rotted away, but they are original. Not bad for 15 years.
I still have the original iron grates/griddles and they are just fine.
I use olive oil before every use (once hot) so the grates will last forever.
I only get a few years out of the striker, but am thinking I won't replace it this year as I use one of those el-cheapo lighters from the dollar store. And no more WOOF when I use the lighter.
My bucket is still solid as a rock. I only clean it every year or two. Putty knife and a shopvac to remove all the encrusted grease.
Maybe it's lasted this long because I don't clean all the grease/oil out.
I learned long ago to NOT clean a BBQ too much. The leftovers protect the internals. Just keep it clear of stuff that can cause fires/flare-ups and you're good to go.
My dad mis-understood me years ago.
I told him to never clean his unit before winter. This protects it from rotting.
So he never cleaned it - ever. His unit had a stainless deflector over the burners. It caught fire one summer. The deflector melted and adhered to the burners
