Sander's fix with POR15 has been the "standard" for a long time, but some tanks(2 recently) have been "worked/fixed" by another method so they are no longer repairable without an inordinate amount of extra time, thus making a replacement one a cheaper alternative, especially if it's aluminum or some other non-rusting material.
Sadly, aluminum is not resistant to corrosion. It is very susceptible to salt and water, but instead of turning into red, crumbly corn flakes, it turns to white powder.
It is the water in gasoline that rots fuel tanks, and aluminum will likewise suffer if the fuel contains water. I suppose it will last a bit longer that steel under the same conditions, but after 50 years who knows?
Aluminum blocks and heads will get severely corroded if the coolant is not replaced regularly, since the corrosion inhibitors are depleted over time.
Just something to be aware of. Maintenance is still needed, even if a component is made of aluminum.
