Tips on keeping water/ice build up off? "Water Resistant Silicone?"

I believe I saw someone post awhile back (could have been FB) about using a “water resistant spray silicone” for keeping water off the bulb seal on the tent. Had an interesting experience and not sure if it would have helped but basically had some light freezing rain which turned into snow and had some trouble closing the tent this AM. Nothing a little heat gun couldn’t fix but curious if I can potentially mitigate some of this next time. This is def a one off situation and not likely to happen much either.


Need a baby ice scrapper!
