All I can say,
If I were looking for a syrup kettle; I definitely wouldn't want to take the chance of screwing up the patina with a finish. It's lasted this long. Adding oxidisers & water will speed up any corrosion as already stated.
If going with something similar(expensive); but not vintage, I'd probably just use a Rino lining type product. Have it applied at/below water line. Just out of view.
Of course, it'll decrease value as bad as or more of the vintage value.
