If there's room for a pump-up canopy seal, maybe a tubular silicone rubber
seal would fit? Stemme uses one on the S10 and it seems to work well.

Silicone rubber tubing has a broad temperature range, can be had in many
sizes, wall thicknesses and degrees of firmness. McMaster-Carr has a good
selection. You have to attach it with silicone rubber sealant (RTV), or
mechanical means, as other adhesives generally won't work.

all the best,

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.
