29 Windshield help

[rinzana]

Hello,
Getting back to work on my 29 Fordor. Need to change the rubber that hold the windshield in the frame and paint the frame. So far I have removed the top of the frame and hinge.
How do I remove the glass from the bottom part of the frame? Is there a trick or just pull?
Should I clean and paint the frame before or after re-installing the glass? Is there a trick to re-installing the glass?

Thank You
Rich
