On my Legacy, the clearance between the
canopy frame, instruments/avionics and panel was so tight that I didn’t have
the room to apply a leather or some other cover material to the dust cover.
As such, mine is simply painted satin black. Not as elegant as a cover,
but it looks OK and is lighter. Note that I may need to repaint it flat black
as the glare gets pretty bad at certain sun orientations. So far, no burn
problems. Also note that I made my dust cover by cutting and combining two
dust covers; the old style one (with the “hump”) from Lancair and a
new style one that I purchased. After bonding the two together, I still had
to perform some “shaping” using the good old heat gun in order to
mold it around the instruments. Not perfect, but done!

Charles,
Good points.
Any thin metal will work even aluminum foil.
The only rub is making it not ugly..

What about a small patch of thicker dull black anodized aluminum, or
even better, blackened copper? The marks I generally saw on my plane
and others looked to be primarily melting the plastic. I recovered our
dash's plastic that had several melt "burn" marks with leather and
ended up with one more scorch mark on it -- not a big one, but still
visible. So my t thought is that if the aluminum is thick enough, it
will conduct the heat away and spread it out. That's why the alternate
material of copper would be even better, very high melting point, and better
heat conductivity. What I'm less clear on is the black copper coating
durability. Anodized aluminum coatings are extremely
robust. So the best of two worlds -- bonded aluminum/copper sandwiches
like our "silver" coinage. The anodized aluminum up, and
copper underneath?
