Dear Fouad,

Many procedures are developed to protect copper specially in out door but this is simple and practical one:
1-polish the surfaces of copper[mechanically]
2- degrease the surfaces of the copper objects
3-plate this surface with clear coat [electro statically] on Egypt wither give 5 years grranty for rust
