My buddy laughed when I pulled out a can of a product that plumbers use called Nev-R-Seize. He watched me jack up my new boat trailer, remove the wheels, and coat the threads and lugs. "That's a waste of time," he said, "mine always pop off when I change a flat tire." Well, he got a flat on our way to launch his boat for a sea duck hunt. And guess what? He was right. We jacked up his trailer and with one strong torque with his lug wrench, and he snapped one cleanly off. "Next time I'll try your goo," he said.
