Hey Pete.
I glassed my canopy as well, but last week I saw an excellent installation using aluminum. It was very impressive.
The fellow described how he used custom-made spacers/standoffs under the aluminum to support the strips. It struck me that some kind of 'mixed' approach would work well.... bed the windshield in place with a flox-mixture, then cover everything with aluminum strips attached with screws that are threaded into the flox.
I don't have any photos, but the final install looked very good, and I'd consider it for my next plane (don't tell my wife). I don't think the canopy to windscreen seal would be as good as a fully glassed method, but it would be lighter.
Based on where you are in the project, you are getting close to completion. This fall?
