OK. Here comes Mrs Duh.
I've lived in the same home for 11 years. Have a double bay garage door. Never oiled, WD-40'd, wiped, or in any other way even looked at the thing. Not even sure where all this equipment you're discussing is located. Have no trouble with it.
Now I suggest you all go to your neighborhood bookie and bet everything you own that the door will fall from the track and smash both of our cars to smithereens tomorrow morning.
You can take that to the bank!!
