Tom, I'll just be honest and say that I was very non-scientific about the
application. One can "feel" where the forward reinforced portion of the
root comes to an end, below where the windshield and canopy meet (or a bit
forward from there). I masked the area off and started painting.
The outboard edge was had by running a piece of masking tape inboard of the
rubber wing seal. I used 1" tape. That provided a nice gap and a straight
line.
As for the forward-end shape, I first made a straight line from directly
below the windshield frame straight out to the wing seal. I then went 6"
forward of that on the inboard side, and taped the front edge of that
"triangle" so the walk would have a bevel. This remained over the
reinforced portion of the wing root.
As for the inboard line back to the trailing edge, well I just threw down a
piece of tape and made it look straight, and made sure it covered where any
feet might go. On the other side of the plane, I threw down another piece
of tape and tried to make it look symmetric. I took a couple of
measurements to double-check.
I added some extra tape outbound from this pattern to cover over-brushing,
and it worked out nicely.
One thing I had to do, as this paint started to "set up", was give it some
very light, almost decorative brush strokes to even out pools that were
forming and to get the brush lines uniform and half-assed professional looking.
I did have a little seepage under the tape, unfortunately, but this was
covered by a black/yellow safety tape border I added after the paint dried.
As for airflow, no I didn't worry much about that. Anything was better
than what was there. What I put on there was better than what it had ever
had before.

Hi TG:
Great idea Bradley.
If I my add my findings on the air flow issue of this topic. I have an AA-5
and I just did some tank sealing work, the rubber wing root seal was removed
and while it was off I took the plane of a couple of flights. I checked my RPM
Vs IAS and did not notice any ... not a bit of speed difference with the
rubber seal totally removed. So my quick conclusion is the area from the seal
to
the fuselage side is so aerodynamically dirty that the seal does not make any
difference, and/or the laminar air flow begins further out past the rubber
wing root seal.
This may also be the case on AA-1's so the type and size of the wing-walk is
not an issue, just a visual concern.

Bradley/Barry,
thanks for the responses. I can definitely do a neater, smaller,
cosmetically more appealing job than what was on there.
