 He said, do you have any ideas? And, of course, I do have lots of ideas because our shop has a lot of electric doors. I would say four, six, eight, somewhere between eight and ten electric doors at the shop. So we have a lot of experience. And one thing that we found is after a period of time, they get dry and they just start making a rattle noise. They don't recommend putting any kind of grease on a garage door, at least the garage door experts that I have talked to.
