“We were on our way home when the radiator in our motor home sprung a leak with water running out faster than we could pour it back in. We added a can of Dike® temporary radiator stop leak and some water in the radiator. In only a matter of minutes, the leak stopped and we traveled home safely. Now, we never travel without Dike.”
