My home windows are the old accordian style. I want to replace the rubber piece (gasket) that runs around the window. Besides trying to find the right size is there anything special I need to know to do this. Does it stay put when pushed into the groove or does it need silicone or something?
Any info is appreciated.
Thanks

Hopes this helps.
