You can see in the first picture that I have taped off the first two rows of panels. I like to work on two rows at a time then move the door up and work on the bottom two rows.
The next photograph shows the door after I have finished painting all the center panels in. Then I move the tape and paint in the areas between the panels.
Almost done at this point in the process. Once the horizontal areas are painted in the only part left to paint is the vertical area on either side of the door.
As you can see from the next photograph of the door you actually have to walk right up to it to see it is not really wood.
