Canopy glue is almost foolproof. It's so easy to get an excellent job that it beats everything all hollow.

Mark out where the glue is to go on the fuselage. Wipe the canopy glue along that "line". Q-tips work great. They smooth out the glue so you wind up with the perfect amount. You'll have sufficient glue and it won't dribble off. You don't have to be perfect, but stay close to the lines. Now, use a Q-tip and wipe canopy glue around the inside perimeter of the canopy where it will touch the fuselage. You don't have to be too neat, but try not to be sloppy. You don't have to beat your brains out keeping everything perfectly clean however, because the canopy glue is very forgiving. More on that later.

After you've got the canopy prepared, the glue on the fuselage will have gotten nicely tacky. It will help you hold the canopy where you want it. Have a couple of long strips of masking tape ready and put the canopy under slight tension with the tape.

Pressing and taping the canopy in place is going to squeeze some glue out. No problem. Matter of fact, it's actually a good thing. It insures you've got a good seal. Take a wet paper towel and wipe away any squeeze-out. The glue is very forgiving. It cleans up easy. It also allows you to settle the canopy with no bulges. Screwing on a canopy often leaves gaps and bulges. Not going to happen with canopy glue. Epoxy can be awful to work with and any smear is usually a catastrophy, or at best a tough job to clean up.

If you see any excess canopy glue inside the canopy, don't sweat it. It will dry clear and become invisible in a day or so.

It's amazing stuff.
I used to hate gluing on canopies.
I got one to do tonight for the P47. It'll take about 10 or 15 minutes and will be perfect. I actually look forward to it.
