Quite happy so far, although not keen on the shot-blasted finish so have decided to sand it down and polish them by hand (at least the front surfaces). I think I could have left them in for longer but didn't want to risk eating into the metal itself.
I might also do the extractor bolts and hardware... let's see how it looks with them black first.
I'd offer access to my polishing machine but with Covid (my mother in law, in the vulnerable category, is in our support bubble) you'd need to come pick it up. You're welcome to do so, if can be bothered, and have access to a car ideally...
