Applying finish to a Teak plank

After being done with planing and sanding if I wish to give a Teak plank a glossy look as well as waterproof it, what would be the best way?

If the plank is coated with a Teak Sealer, and then coated with shellac and finally coated with beeswax, would the desired results be achieved? Would it be the best thing to do? If not, what could be a better way? Kindly advise.
