I am wondering if anyone here has experienced the wonders of Dri-Slide. Around these parts no one has heard of this amazing substance and the miracles it makes possible. This lube will free up almost any stiff or sticky cable. You can apply it to one end of the cable housing and it will flow all the way through the housing, a couple pulls of the cable and it's good to go. It also does wonders to cables that are going through very tight turns as well! It's great, I have finally converted all of the guys at the shop where I work and now they love it too.
Oh it's available from QBP, retail would be like $10 per bottle.
