The individual slats from 1" plastic venetian blinds (K-mart, etc.) are a
great raw material for wipers. Strips 3/8" or so wide can be cut from
either finished edge.
If the wing is skinned foam core, a slit is made between the two with an
Exacto knife and a thin sanding tool such as the fine, flexible Permagrit
can open the slit to the thickness of the slat to avoid a bump. The slat is
pushed in about 3/16" and secured by wiucking in place in a few spots with
thin CA glue between slat and skin. The slat has some curvature, but is
easily bent more, as needed to clear the wing skin, before installing. It
can also be spray painted in advance to match adjacent colors. On the wing
side, clearance for the front edge of the wiper can be made with a round
sanding tool.
I put these on the flaps of my GENIE #18. It took only a few minutes and
added a real nice touch, getting rid of the open gap and helping to keep
out dust and dirt. Looks a lot like they are part of a molded skin. See
