I've used silicone lube in the felt channels, cleaned the channels, lubed the regulator mechanism, all kinds of attempts to fix slow power windows. Not much improvement, and silicone on the glass sucks.

When they got so slow last winter that they'd barely move, I sprayed in some graphite powder and it seemed to work pretty well
Now the weather is warm again so they work better. I can't tell if the graphite is helping or not. I'm wondering if anybody else has tried graphite powder and how it worked for you?
