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.

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?
