In the proactive maintenance thread there is talk about garage door springs. I dont get it, why do we lube them? I assume it is more to prevent surface rust than to actually lube the spring. And people talk about inconvenience... I assume the door is heavier, but come on, not that terribly much so... What's the big issue if one fails (besides falling on my car). if replacing, should they be painted with rustoleum or some similar anti-rust coating first?
