I am about to install a copper weathervane which will also work as lightning conductor (it will be mounted on top of an earthed aluminium flagpole).
- exposed to weather, copper will corrode and become looking like the Statue of Liberty; and
- I want the weathervane to look white/silver/metallic
— I am looking for options to coat the weathervane with conductive metallic layer which will:
- Protect copper from corrosion
- Be electrically conductive
- Look white/silver/metallic
Products like EMI/RFI shielding would perhaps be ideal for the purpose, but the problem is that they are not available in New Zealand, and they are classified as dangerous goods to be shipped here by ordinary mail (except for water based, but this won't be weather resistant).
I am therefore looking at making conductive coat myself from aluminium powder.
What kind of base/resin should I use?
