You know my opinion Michael, but here it is again for everyone:
Having seen this thing in person, it is incredible. By far the coolest kettle I have ever laid my hands on. Not even close.
Also, I saw Mikey's nail polish in person with the kettle. It is frankly a better match than any other color match on any kettle I have seen. It is spot on.
That being said ....
I would leave it as is, and not continue restoring. I know this is not a cooker, and you do not plan on cooking on it .. but ... what if you wanted to? And, IMO, every Weber should be ready to be called in to action when needed.
You have done an incredible job cleaning this up.
