How do you paint a wood window that is inside a storm window.
You have to remove the storm window to paint it. Lil tip put the storm window back on while the paint is still tacky and it will help seal it off from outside elements
Unless you windows can pop out into the house, you have to remove the storm window and paint. Then reinstall the storm window
I think if you are to reach the wood window effectively, one of them has to come out to access the other. Remove the easier one, paint and restore.
