At the Little Brown Bungalow I have installed a pair of French Doors to the outside, and I am using a plank of hardwood (sapele) in the inside reveal to give an attractive threshold and a tidy edge to the carpet.
The installation method is not complex: Stick to Sub-Floor.
The question is what to use as a finish for the sapele.
Plan A is Polyx Oil, which may not be water fast if eg it gets rain blowing on while the door is open.
I am wondering whether a slightly more extreme Plan B finish, such as marine or exterior varnish, would give me a longer life-without-maintenance.
Comments would be welcome.
