    Works great, very expensive
    I got this to potentially replace RIG grease for use in protecting Firearm barrels from rust which is a big problem in the deep south.Seems to be top notch for preventing rust so far. I did an unscientific test with this, RIG grease, and Hornady One-shot during a cold raining December. It has been 5 days in the rain, Hornady One-Shot which has ACE'd other online tests failed at day 2. Only the RIG grease and WD-40 Specialist LTCI are preventing rust (See photo). Looks like the WD-40 LTCI might be starting to fail but... for being on raw iron almost submerged in water thats very impressive. RIG grease has absolutely not one spec of rust on it.People have commented it gets sticky. I do not see this at all, it ends up more like a common grease type substance.Two problems: #1, the can is way overcharged on propellant, its impossible to dispense this except in an explosive manner so it gets everywhere and way too much. And #2, its way overpriced to me. The can is so much smaller than all the other specialist products, its almost a joke how small it is for how much they charge. Considering a big jar of RIG grease is about the same price...it will be hard to make me switch.
