Spent 2½ hours yesterday aligning my left door window in the Longchamp, so it can slide freely, so the electric motor can close it properly. Finally got it working, which involved modifying the central channel, cutting off the lower bracket and welding it on on the other side! Strange because the door fits perfectly on the car, no damage ever.
Question, what can I use on the black material in the frames so the window slides even easier? Graphite, silicone, grease, oil?
