Follow up on the use of sheet metal screws to hold on the canopy. In a previous post I included a picture of a ShowTime 50 canopy held on by 6 screws along the sides with film over the leading edge.
I just did an engine run-in on a bench at the field. Surprise, the 2 rear screws no longer help holding the canopy on as the canopy cracked and broke around those two screws. This wouldn't have happened if a canopy glue were used.
Good example of what can happen. Useful post.
I frequently use matching or contrasting covering as a boarder around the canopy on sport planes. War birds are always painted, so that is used over the canopy 'frames'.
I found that Ultracote is nice to use because it requires less heat. It can actually be sealed to a canopy if you keep the iron moving and don't build excessive heat.
