How do you secure shut MC9 windows after removing the emergency exit bar?

My methods of sealant and great stuff spray foam have finally let me down.

Leave the latches.



If that is not an option run screws through the window frame and into the bus frame around the window.  Mine are that way when purchased. i would prefer the latches.

you have picks of issue?
