Lay the fiberglass mats over the crack on the inside of the bumper. Be sure the mats are pressed flat against the bumper insides and that there are no bubbles.

Allow the epoxy to dry as long as required by its instructions.

The repair is complete once the epoxy dries! If you wish to further conceal the damage, follow our Body Work Dents and Cracks guide and Hand Painting guide to make the bumper truly look like new!
