The issue is you need to recoat sealants every 10-15 years, you only need to chat oxide every 50 to 100 to access damage and most of the damage is on the internal iron structure that the dielectric force is slowly eating at a faster rate then the copper skin.
There was a bunch of news about it around iirc 1980 when they cleaned sections to rebuild the inner scaffold in some areas.
I mean maybe but we did that already out was the 1980s and they had to shut down and iirc permanently close the torch lookout.
