The first coat of paint on it is all brown. The next coat will be the darker green color in the panel areas and the trim will remain as is. I wanted to mount it this way to see if we would like it - but its too much of the dark color. Either way, I am happy with the way it has turned out so far.
Mounting the door in the box-rail track was simple, it just required a second set of hands due to the size and weight of the door. Now I need to fabricate and attached the stop-blocks at each end and the latch hardware.
