Review on Grams of Tacky Soldering Flux for Easy Cleaning by Michael Hughes

I'm not very happy with this "flux", I haven't had that tube in a long time and it's already all gooey through and through when I apply it's hard to get out of time to time because it seems a bit hardened and when i get it out i can say it's definitely a little hardened, if i had no less than half left i would return it but i MUST use it, I was in a dilemma and couldn't do without it, there's a chance my experience doesn't match YOUR experience, I feel like maybe I just accidentally got an old syringe or a bad batch?
