Good idea, great idea, or bad idea? My wheels squeak and this is on the todo list.
I have teflon spray (interesting)
I've got white lithium grease too.
ps. I currently have one spot my dome eventually seems to pop its wheels out of, I'm going to try using teh scuplting epoxy to keep it in its track. One concern I have is will this make this less a problem or more. I tend to think greasing the track will reduce popout events and help the dome stay evened out.
