The lube is a quality lubricant and the performance is great when using it on your bike components. Park tool is a reputable brand that exceeds other manufacturers' industries in tools and lubricants for bicycles.
When doing my first ever (I've done two now) pedal change on a bicycle I was told to use this product. It seems to help the pedal screw in smoothly and easily. I recommend cleaning the crank first as it seemed to have residue from the original installation as well as some other grime. I don't think my incredible shop would give me bad advice.
