My Discus2 canopy and frame fit a little too tight to the fuselage
making closing difficult or impossible when it really heats up. In
the winter it was much better, but still a bit tight. At normal
temps. in Florida (90 to 95 degrees this time of year) in the shade,
it is clearly too tight, since even when closed the frame is not flush
with the fuselage and it takes a good deal of force to close it which
can't be good for it.

I've tried waxing both interfaces, and it is better, but still not
flush. It seems that a light sanding is in order where contact is
made.

Any good advise on what grade of paper to start with and a progress of
grits and whether the sanding should be done on the frame or fuselage,
or some on both.

Any good advise is appreciated.

Thanks-
