Hi Bill,

Here's my post on the same topic a few years ago. I assume = you're=20 asking about the inflatable seal? I now have five years and 500 = hours on=20 my Legacy and the canopy seal is still fine.

I used blue masking tape to hold the inflatable canopy seal in = place before=20 gluing it. Since the seal is stretchy, if you're not careful, you can = scrunch it=20 up so that it is too short or stretch it so that it is too long. I kept = removing=20 the tape and putting it back on until I felt like I had the minimum = distortion=20 throughout the length of the seal.

Once I was happy with its placement, I removed the masking tape in = a short=20 section and pulled the seal away from the fuselage and applied the = silicone=20 adhesive that Lancair includes with the seal. Pressed the seal back into = place=20 and put new masking tape to hold it there. I repeated the process in = short=20 sections at a time until I was all the way around and back where I=20 started.

By the way, it had been over two years between buying the canopy = seal (and=20 the included silicone adhesive) and installing it. To be on the safe = side, I=20 bought a new, fresh, tube of silicone adhesive from Lancair.

There doesn't seem to be much, if any, friction between the seal = and the=20 canopy when the canopy opens and closes, so I didn't put a huge amount = of=20 silicone adhesive on it. Silicone adhesive is hard to clean up without = smearing=20 it and making a mess, so I tried to get on just enough without a lot of = squeeze=20 out.

I also protected the tube that sticks out of the canopy seal that = attaches=20 to the canopy pump because my glare shield sort of rubs on it. I was = afraid that=20 vibration would eventually rub a hole in the tube.

I turned down the pressure setting on the canopy seal air pump to = its=20 lowest setting, probably less than 5 psi. That's enough to effectively = seal and=20 more pressure was lifting the canopy away from the fuselage. You might = want to=20 experiment with that in the hangar. I can't see any benefit of more = pressure=20 than you need.
