The air noise seems mainly a matter of a good canopy seal. Is there a good
sealing material that anyone has found? I've tried commercial foam strip,
but it's rather too thick, and smears to a gummy mess after a while.

My canopy seems to seal well without a gasket. However, I've seen an
external seal that looks like a smaller version of a aileron gap seal
and was told it's available from hardware stores.
