RC56 and F560 work great. Shake the bottle and it isn't runny.

I actually like the somewhat thin consistency. I run a bead around the inside of the canopy and smooth it with a Q-tip. The Q-tip either removes excess or pushes it over to areas that were too thin. Set the canopy aside and do the same application to the fuselage. When you've gone around that with a Q-tip, the glue on the canopy has gotten some tack to it. At that point, I take a bit of time and tear off a couple of strips of masking tape the right length to hold the canopy down. And that lets both glue applications get a bit more tack.

Place the canopy, adjust it, press lightly and some glue squished out some places. Wipe that with a wet paper towel and put on the masking tape. Any more glue squeezes out? Wipe it off and walk off.

And excess that squeezes up inside the cockpit you just ignore. It's going to dry clear.

Never seen any product that so perfectly fits the job. Dead simple and easy to do. Great stuff.
