[TowerTalk] tower base rod weatherproofing

[bob]

I have some non-galvanized bolts/rods embedded into a concrete base for a
short tower mounting plate.

 

What would you recommend to coat them in to keep corrosion/rust demons away?


 

They are composed of hardened 5/8 x 18 threaded rods (non-galvanized) and
the bolts are used for adjusting the tower for plumb, so I'd like to
preserve the ability to adjust them at some point again.  So something that
would leave the nuts still adjustable down the road is preferable, even if
has to be re-sealed/coated at that time its fine.

 

Suggestions?
