Squealing rubber seal on slideout

[Bears_Den]

When opening and closing my slideout the weather stripping squeals when the rubber meets the two side windows. Does anyone have a solution? I was thinking of spraying some weather seal treatment on the glass to get the back side of the seal. Any ideas would be appreciated. No substitute for experience.

Happy neighbors are good neighbors. 303 Protect All is your friend. Good luck on the squeal.

I use ProtectAll on slide windows and frames. Keeps them clean, and slippery. I also put baby powder on the slide wipers, which makes them slide easily, and quietly Just the side wipers, not the top wiper, which needs to be a bit tacky. I use slide wiper conditioner on the top wiper.

Get some silicon spray and wipe it onto both sides of the seal.
