As well as locking the threads, Loctite is designed to seal them against 
penetration by water and moist air, so it's one of the best things you 
can possibly do to prevent corrosion.

That was mentioned back in August, and it's probably the best solution 
if the threads in the casting are already too far gone. You'd have to be 
careful to select the right grade of hard-setting, gap-filling Loctite.

If you need to shrink your T2X down a little, Jim Lux has some 
interesting suggestions...

As Jim said, we trust our lives to thread-lock every day.
