Rich, I grew up with teak furniture, and still have some pieces more than 50 years old. Our bar and table tops are waterproofed with normal white floor wax, a thin coating once per annum. This also guarded against the greying effect. After this many years the furniture still looks like it was made last week. If you start using teak oil, you have to continue with it, as it leaches out the natural teak wax.
A beautiful wood, easy to work if you go at it slowly. Enjoy the build
Mistakes are proof that I am trying....
Now to remember what!
