I guess the taping was so effective that the gold paint job was dropped with the later APH-6(mid to late 60's). They were issued standard white, and generally speaking, pilots applied their own individual taping patterns.
This APH-6D of mine has had almost the entire shell covered with white reflective tape, much like chevyfan's SPH-4 in this thread. It has a minimal amount of red tape over that.
As another example, this APH-6A has intermittant red and white tape applied.
From what I gather talking to people, there was a bit of skill involved to do a good tape job.
