Find out what the dealership uses via the parts counter; see whether you can buy the same stuff.
Seals are best lubed while hot and expanded; from the car sitting in the sun. Try Liquid Wrench brand silicon spray; and into the forward most and rear tracks.
What I'm about to suggest may have you cleaning streaks/smears from your window for weeks. But the glass might also be making contact with the rubber trim along the bottom, both inside and outside of the vehicle. Be careful not to damage that trim by pulling it back too far. Need just enough gap to get the straw in there and add a *little* lube along the bottom of the window.
BTW, using that stuff on the door jamb seals, helps keep the doors from freezing shut; and/or the door seals from getting torn up. (Ice doesn't cling to the rubber.)
