I'm sorry I don't have direct experience of your issue.
I just wanted to mention that, if you choose a different metal
then Stainless is preferred, because of bi-metal corrosion - Al
or Cu with iron will rust the iron quickly - a
coupling/extension/cover of some sort would be ideal - if painted
it should resist UV sunlight too (if relevant of course).
