Window sash removal
We have a 1972 27 ft international airstream. We have the service manual that seems to show how to remove the window sash so that we can remove the outer glass pane. The sash seems to be attached with a foarm double stick tape around the outer rim of the sash and a double stick butyrate tape that separates the two panes of glass. The manual shows using a screw driver to pry out the sash.
I have read a few articles on the internet saying a different way and seems very hard. Any comments please
