I like Liquid Wrench products even though they are hard to find in stores. Looking for a penetrating lube, I found a YouTube review of several using a torque wrench to measure how well each rusty bolt was loosened. This one came out on top and it wasn't the most expensive so I went ahead and bought it. So far I've only used it on the rusted end of a hose but it has worked flawlessly so I'm selling for future projects. I think the only thing I can complain about is that I always lose my straw in these things. I wish there was one on there, like WD-40, but that's a nitpick at the moment and definitely doesn't deserve a star. There really isn't much more to say about this than I recommend trying it out.
