yes spray on silicon spray lubricant. i use prestone i get it from walmart. wd40 will dry out the rubber. silicon spray will not. i roll the window down and i start at the corner by the mirror then i go up the rubber weather strip and then down the back and spray down inside the door at both ends. then i roll the window up and down to move it around. u will have some at the top of the window that is no big deal until summer then wipe it off it will make the window stick to the rubber. i do all 4 windows. u can use this spray in the door locks and door jams trunk lock. honda windows love to rattle. dont roll the windows up or down when the car is moving that will help prevent them from becoming loose and rattle. avoid rolling them up and down esp on the expressways. adjust them at complete stops.
