weird window rubber problem

[texomawaves]

I noticed the rubber weather strip outside of the window catches and curls down when I lower the window. This adds a lot of drag to the window motor. So... I'm wondering if anyone has a remedy or a DIY to replace the weather strip. I applied car wax to the window (to slick it up) which seems to help for a week or two, but the rubber may be chemically breaking down. WD40 perhaps? lol
