It's real easy to get high grade stainless rod.
I just chuck it in the lathe and thread it as needed.
I use a special moly anti-seize mix now days.

You can get a 60% mix from Honda. WalMart and most Auto Parts places sell a lesser grade.

If you get the good stuff? Be sure to wear rubber gloves!
That stuff is wicked evil!
