Something I think is sticky in the window track as I hear this annoying screaching sound when I first roll down or at the end of rolling up the window. Goes away when it's raining and the window is wet.

Any tricks to getting rid of this annoying sound without removing the door panel?

 

I know you can use TurtleWax Ice quick wax on windows/glass...
maybe the outsides "rough" and makes that noise against the glass...
Its sold at walmart.

its by no means a serious detailing product but for me it does a good job at hiding scratches and swirls after washes

 

Only way to find out what it is is to remove the door panel.
