Jamie is correct. In my case I use the 3M tape that is often used to cover the seams on gliders. Also if the mechanism is to be used in flight, you have to remove the "gas struts". The original RVs didn't use these struts. We have a flip up strut that is totally disconnected when the canopy is closed.
Of course none of this applies if you intend to use the mechanism for maintainence only.
