Lots of options out there for finishes. CA is a good one, but, as Greg said, it will show wear over time in the form of scratches and chips. I personally don't do CA for this reason and the fact that mine at least give the call a "plastic" feel that I don't like.
A good working finish is to submerge in teak oil or Velvit oil for a day, wipe down and hang to dry then buff.
Dipping in spar thinned with mineral spirits is also a good finish to get a glossy shine. It takes some practice to get it to finish without runs/drips but is also a great working finish.
Teak oil and spar are my two finishes of choice. But, the Massey finish is on my short list of things to try. For those who use it, it produces the high gloss of CA/spar but seems to also offer high durability.
I would avoid the friction polishes. They produce a shiny finish pretty quickly. But they dull pretty quickly too with handling and aren't a good working finish.
