Might help with corrosion, too. My grandfather had a very old garage door and opener, and one day something gave and it blew apart. It sounded very much like a shotgun had been fired inside the garage.
Fortunately, nobody was in or near the garage when it happened, but I'll remember it every time "garage door spring" comes up in conversation.
We had a corroded one that still functioned but I finally buckled under the RACKET the thing made every time the door opened and closed and got it replaced anyway.
Every single time you opened or closed it, it sounded like a goddamn car crash going on out front. Ugh.
