Default Help! Leaky Hot Water Tank problem!

My Electric hot water heater / PVsolar+heat pump Storage tank is leaking.
It seemed to be leaking around the Anode port.
I pulled out what was left of the Anode and ordered a replacement.
Anode rod
Made from aluminum
42" long
5/8" outside diameter
3/4" -14 NPT

Standard stuff. Installed it using Rectorseal 23631

It leaked, so I tried again. Still leaked.
Cleaned it up and tried Teflon tape/PTFE and it still leaked (very slow).
Cleaned it up and tried using 8 turns of 1" wide PTFE, it's still leaking!

Since the water heater is about 5 years old, I'm thinking about using
some kind of Cold Steel epoxy to permanently seal the Anode,
since the tank is already very near end-of-life..

Please impart some expert advice!
