I just got a blue gen 2, its the most worn out kettle I think I've ever seen. The burner tube was salvageable, but the sweeps dont appear to be stainless to me, or if they are they had so much rust fall on them that they rusted out.
And I did nick the bowl of my ssp while grinding off the nut for the lid bale. It will season though.
A lot of people recommend not touching up the paint, you can just put cpoking oil on it while your cooking and it should season like cast iron. I painted the edge of the lid on my first kettle a few months ago and it already looks faded. You can't match the gloss of the porcelain, so your touch ups are gonna stand out either way.
A big ol butcher block top would sure look nice on there, Idk how heavy of a top you can put on one before it becomes unstable though.
Whatever you do to it, post pics!
