Many windshield repair technicians try to save a dime or two by using the same end seal over and over. But those technicians may not know that by over using an end seal, they are compromising the repair quality. It is likely wasting expensive resin.

After 10 uses, the end seals begin to break down and get softer. The inside diameter of the end seal is smaller than the plunger to provide a leak free seal. After repeated use, the hole becomes enlarged, eventually resulting in loss of pressure. Loss of pressure can create leakage of resin, which results in wasted resin, and makes it difficult to ensure that the damage…. Read More
