Years back I sealed my LS-6a canopy perfectly by first draping plastic
wrap over the entire canopy opening and securing around the edges with
masking tape. I then shot clear silicone around the groove in the
canopy, locked the canopy down and left it for a day. The next day I
opened the canopy, removed the plastic wrap, and using a razor blade,
trimmed off all of the silicone that squeezed out. Result: a perfectly
sealed and quiet canopy.

Great idea, but others should be sure to clamp off or disconnect the pitot if it is in the nose with the air intake. Another leak detector that works with this method is one of those "punk" firework igniters. It produces smoke and can be waved over the canopy gap to show escaping air. A cigarette will also work, but I am not so politically incorrect to suggest THAT! (although it is what I use)
A piece of instrument tubing used as a stethoscope in flight can help find leaks too.
Don't confuse it with the pee tube.
