Looks good, how much is it? I keep a spray can of white grease in the tubular operating manual container on my backhoe to spray the cylinders when I'm not using them.
if I remember correctly it's like liquid wrench. I used it to free up my old mustang engine. Let it soak and it will work. I also used it to loosen the bolts on my chippers flywheel.
This is a rust inhibitor, leaves a pretty heavy film, wont dry up as fast as WD-40, made by the same company that makes the super break free catalyst for loosening rusted fasteners.
Not sure of the cost, maybe $5.00? it goes pretty far, JB.
