Sealing The PIK-20B Canopy

CRUMMY!!
This is the best description I can think of to describe the pump-up canopy
seal on my PIK-20B. The concept is good, since like on most side-hinged
canopies, the sealing surfaces are both horizontal and vertical. But in
practice the seal never was great and it leaks so re-pumping is routine.
(Usually at the top of each thermal, when I can remember).

This winter I plan to improve the seal. I would appreciate hearing from
anyone who has done this or even just thought about it. I am not sure
whether
the best solution is to stay with some Pneumatic concept or go to a
different type of seal altogether.
