Stainless vs electro-galvanized staple externally

[mattiasj78]

When stapling wind barrier and roof underlay (assuming you have a "staple-friendly" variant), do you need stainless steel staples, or are electro-galvanized ones sufficient...?

not electro-galvanized... Hot-dip galvanized works... but rf is awesome

where can you buy stainless steel?

We found a stainless Rapid variant in the building trades store. But the thing with staples is quite a jungle. Every manufacturer seems to have their own dimension. The stainless ones I've seen are 10.6 mm wide. Does anyone know where I can buy a 10.6 mm staple gun (pneumatic)? Or what other stainless widths are available?
