Nice job. What metal did you use for the window frames?
The frames are plastic trim, (u profile) just pushed over 3mm lexan, which is the screen. I heated it with a hair drier, and pushed it over a wood template when it was soft. I was after "proper" glazing, not thin plastic sheet!
After some time, water has ingressed behind the chrome paint, due to the prep of the plastic not being as good as it could have been, however the metal parts such as alloy and brass have remained perfect
