Hi,

Now that our new windows are installed, we plan to use a clear finish for
the interior pine, such as a satin water-based Urethane.

Is it best to use an exterior grade finish, or is an interior grade fine?
I think some rain will eventually wet the surfaces, since we'll probably
forget to close a window, or will be hit by a surprise rain storm.

To prevent staining the wood, the contractor said to first apply one coat of
finish before filling nail holes with a pine filler.
Any other advice is welcome, too.

Thanks.
