Suggestions to stop track rod end nut rusting?

Does anyone have any suggestions to stop the track rod end nut / threaded section from rusting?

They've only been on a few months and I've managed to round the 7mm on top trying to loosen them, so now they're getting destroyed... I might just be heavy handed, but it feels like you're fighting a losing battle trying to get it off in once piece !

Cheers
 
Using an impact gun helps.
Failing putting copper grease on the threads, there's not really much you can do about it.
 
There’s a few things you could try;

Regular application of ACF50
Smear in copper grease
Wrap in electrical tape to hide threads
Zip tie a finger of a latex glove over the threads
