@JohnKSa I agree with everything you wrote. The points I’m attempting to make is that 1. there is nothing objective in a blanket statement in the OP that says, and I’m paraphrasing, “everything negative said on the internet about product X is true”. 2. We’re mostly strangers gathered around a common interest but of many skill levels/habits which, until qualified, leaves us guessing. 3. That by scientific approach the plural of anecdotal is not fact, only repeatability establishes probable causality. If an overwhelming number of users note problems of a similar nature and the common denominator is Frog Lube, a justifiable conclusion may be made. If the problem relates to say one specific model of firearm, of serial number range xxx-xyz and no other, we would certainly want to delve deeper before reaching the same conclusion. I don’t profess to the idea people blindly agree with anything written being fact which is why I cautioned the use of the OP’s statement that the “rumors” were all true. At best he is correct and there’s a faulty lube being sold. At worst the cause of his malfunction lies elsewhere and could cost someone else their life. I’ve used WD, FP-10, Bore Shine, Safariland/Breakfree/G-96 Synthetic CLPs, RemOil, Hoppes, Shooters Choice, Bore Butter, Pro Shot, Super Clean, Rig +P, One Shot, and many more over the decades and not once experienced a stuck bolt. Of course I believe in viscosity, I’ve simply never seen it do what has been claimed with any of those products under the conditions I have faced (which I previously outlined).
