Power windows are slow to roll up or stall completely.

What is your question?

I've noticed on the drivers and passenger windows an after market tint has been applied to the windows. I offer that as a possible additional source of drag. Is there any kind of lubricant (spray Silicone for ex.) that can be applied to the rubber door gaskets or brushes to facilitate a smoother roll up? Or do the motors just need replacing due to 16 years of service?
