Kwila Balustrades

I'm planning on putting Kwila balustrade onto the new deck (75 sqM, wrap around L shape). The boards are oiled kwlia.

The inital plan was to paint it, but now I'm thinking of varnishing or one of the breathable preservativesn like cutec CD50.

It will have a roof on it, but not for a couple of months.

Anyone have any comments on clear finished kwlia balustrade long term, and exposure to weather?

FYI - 2.8m offground and young kids rules out horizontal wire. Vertical wire - too expensive for prefab and too hard for me to do.

Thanx
Paul
