I have had success in finding the tight spots in my
canopy/ fuselage fit by placing a strip of paper in
the seal area and then closing the canopy. Free sliding
paper = OK, dragging paper = tight spot. I sand down
the tight spots then put 3/16 X 3/8th open cell foan
all the way around. Good for a season or two, but the
shearing action at front and rear will eventually destroy
it and so you get to do it again.

The Schleicher canopy fits tightly with a convoluted

room to do so.

Take very small bits of modeling clay (plasticene)
and place them on the
sealing surfaces. Close and then re-open the canopy
to test the clearance.

On my 26e, there's no room at all for any weather-strip.
In fact, the little
bits of clay used in the above test lifted the canopy
ever so slightly above
the fuselage at the forward lip.

all the best,

After seeing the thread about the PIK canopies I wanted
to ask if anyone had taken any extra ordinary steps
to seal an ASW canopy. To date all I have done is
to put some sticky back foam at the front near the
demist vent. It is pretty good but I suspect it can
be better. I have heard that it helps to run the
same
foam all way around the fuse in the depression along
the canopy opening. Thoughts????
