Two alternatives I use:
LPS3 is a heavy, almost cosmoline spray on outdoor rust preventative.
Needs resprayed every 2 years +/- depending on your environment
Spray or brush on galvanizing. Basically a paint carrier with lots of
suspended zinc. Will weather so needs touch up now and then. I
pressure wash and repaint my exposed tower bolts every 3 years, paying
particular attention to the studs at the concrete surface.
Another thing to be concerned about with not galvanized studs after 15
years is what is happening to the studs at the concrete surface and just
below. I'm not a fan of grouting under tower bases as it hides what is
going on.

Fifteen years ago, I had attached a tower to threaded steel studs
protruding from the tower's concrete base. Now, I need to replace the tower.
Even though I used highly recommended "PB Blaster", it was almost impossible
to loosen the nuts from the studs. Finally, I was able to open them, but not
without thoughts of a nightmare scenario where the studs might have been
broken, etc.. I would like to be sure that this situation will never happen
again. I'm convinced that I should have applied something to protect the
hardware when the tower was first installed. I have several ideas, but this
is something I don't care to experiment with for obvious reasons. I'm
looking for something that has actually been done and worked. Any actual
time proven (!) suggestions would be appreciated.
