Those CR Lawrence windows

[pasusan]

I've got a 2004 Roadtrek with the CR Lawrence windows that open in the back. I've read enough on here to see that they come loose and fall off.

I'm trying to prevent that...

I do notice that when opening them they stick to the rubber sealing stuff and it takes quite a lot of torque on the turn handle to get them unstuck and open.

I've lathered the rubber with 303, but that doesn't seem to help.

Anyone have an idea of what to use to keep the windows from sticking? I'm thinking that will help in the longevity of the windows not falling off.
