Sticky door gasket!

Help, please! We have a 2003 Ford Edge and recently discovered a leak in the rear window gasket. We fixed that, but now the drivers door sticks and sometimes freezes shut when the weather is cold. We’ve cleaned the gasket, put silicon spray on it and so far it’s still sticking. Any thoughts, solutions, etc?

Rather than a silicon spray find and use a silicon paste.

Spray bottle car wax might help on the door as well as the seal. Somebody said that spray wax and WD-40 worked well together. Then there was white lithium grease, Lubriplate engine assembly grease.
