I like it; can you get it in long enough sheets (at an affordable price)
to reach at least from tip to inspection plate and inspection plate to
root?

My plan so far has been to try the same technique using thin AL flashing
material from Home Depot a/c supply, but this sounds just as light
without the risk of cutting the wire on the AL.

McMaster-Carr has polyester (generic for Mylar) film in rolls up to 25 feet.

You might also consider Tyvek -- which is a non-woven (paper-like) sheet
made of polyester.
It's used as vapor barrier in housing, but I don't know if it would be stiff
enough.

FWIW, from DuPont's website, "Tyvek® is DuPont's brand of spun-bonded
olefin - a high-tech fabric created" by DuPont from high-density
polyethylene (HDPE)

Howdy,

I've been thinking about how to run wires in an aluminum wing that is already
finished. I can fish something through the holes in the ribs, but I don't
want to just let a wire or cable lay on the raw edges of the rib holes.

Visit your local hardware store. They should have it in rolls of
varying thickness for use in windows, coverings, etc...

One thing about using either tubing, or Mylar. If the stuff is stuck
in place using resin, or even one of the Silastic RTVs it is less
likely to wear through and tubing is less likely to make noise if it
is "stuck" in place.

How big is the wire? Does it really need to go inside the wing?
Sometimes there is room in the flap/aileron bay in which to tuck the
wire. If it does have to go through the wing there have been some
imaginative thought already posted. I like the Kraft paper tube idea
but might sub something that isn't hydrophilic - like the mylar.
