How does the caswell black oxide last? Is it a good long term solution?

I use both the wire wheel and aluminum oxide blasting to clean up hardware and parts. I am looking at either zinc or manganese phosphate coating and using products from somewhere like Palmetto Enterprises or Casewell.... I'm just inquiring if anyone has experience with this and how it will last and or perform on hood hinges and springs etc.
