Re: Spring Lube ?? Additional....
My understanding is that sometime in the mid to late fifties the springs began to be made out of a different steel. The new springs are supposedly not to be oiled or greased. I personally do not understand this next part but if you oil or grease them it will somehow change the molecular makeup of the steel and will prematurely weaken them. Greasing or oiling before the change was recommended.
As a side note if you are sanding or grinding the springs you are supposed to go length wise only, otherwise it will weaken the spring.
