The chip should not be a problem as long as it doesn't cause the roller to jump the track. My 1/4 window roller had a rut worn into it from the tracks being too dry and it would jump out about 1/2 way up. I replaced the worn roller and lubed the track with white lithium grease. I think the same would apply for the door windows.
White lithium is the most common lube. I've used a spray grease before that works well also. I like it because it's easy to use. It comes in a aerosol can with one of those plastic tubes that sticks in the nozzle. The grease I used was red and just kind of foams out of the end of the tube. It doesn't dry up as bad as lithum either.
