Install Cap Rail

What happens here

Measure and cut a 1x2 board to the same length as the top 1x6 horizontal board. This 1x2 board will serve as a cap rail, adding a finished look to the top edge of the paneling. Secure the 1x2 cap rail directly on top of the previously installed 1x6 board using a nail gun, ensuring it is flush and level.

Goal: Add a decorative touch by installing a 1x2 cap rail horizontally on top of the upper 1x6 board.
