With ships, they'll bolt zinc blocks on, can I "re-galvanize" metal?
I ask as I have some flashing that was likely installed in 1938. It was galvanized and is in reasonably good shape. But replacing it would be very expensive and hard, as it laps under the stucco. What can do to extend its life? Or will it rust under the stucco first anyway, making a external treatment moot?
Here's the specific flashing, with two rows of tile removed:

Oh finally a picture. Thank You! Yeah, you could flash over it with galvanized, aluminum, copper or stainless. But, the problem is cutting it in. You'd want to match the cut-in on the chimney all the way up the roof slope's wall. That's to do it right.
But, plenty of guys cover the old with new to just caulk & screw the new stuff to the wall. It's asking for future problems, but if maintained (re-caulked repeatedly) can last the life of the roof.
