Re: rusting stainless
It could be 316L active... But most likely it is some cheap 300 series like 304, or 300. Either way, NEVER SAND STAINLESS. whatever you had, you not have active stainless because you have sanded away the passivated (if there was one) layer. Giver everything a good clean, get the wax off of it, then dip it in a vinegar bath.
This will re-passivated it. It may still rust, but it should be much slower than before.
If it was oxidizing after 3 months, even in Central America, it was not passivated. It sounds like Chinese S/S. I wouldn't use it for anything critical or highly stressed.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
