Leathering Turnbuckles

[glynn]

I have just bought six beautuful bronze Staylock turnbuckles for the same price as a small car in India, so my worry is how should I look after them?

Do I leather them and hide all that shiny stuff, or leave them exposed to the weather and watch them go green?

Many thanks,
Glynn.

P.S. Please do not tell me of any cheaper alternative or I might just weep.
