Fixing spotted gum cladding

[troyt]

I'm a bit of a novice renovator and are looking to install spotted gum timber cladding and searching for advice on both the types of nails and a recommendations for a suitable nail gun for the job.
My place has some existing boards which have warped a bit but these are concealed fixed. My researching on the net is the cladding should be faced fixed. Face fixed nails I have seen on other installations have domed head that look like copper but cant seem to find where I can source these.

Any help and tips on the job and fixings will be appreciated.

you will need to use s/steel or gal with spotted as the timber is treated and will react with the copper nail, (these are used for cedar, as the cedar reacts with gal),

you can use a coil nailer like the duo fast, but i would handnail or screw to avoid spilting
