Usage Scenario

John noticed a small crack in his lawn mower engine block. Instead of buying a new mower or paying for expensive welding, he cleaned the surface with sandpaper, mixed equal parts of the AB glue, and applied it to the crack. After 6 hours, the repair was strong enough to use. He sanded the area smooth and painted over it. The mower has been running without leaks for over a year.
