How have you guys repaired the urethane on a front bumper? I have an 03 cobra bumper and while I was riveting that metal flange with the fixed nuts that go through the fender and bolt from the inside, I tore the smaller urethane flange a little bir that is attached to the cobra bumper. So I was looking for a way to fix it. I hope this makes some sense, I could take pictures, but the bumper is currently on the car waiting for paint after I get this fixed. Thanks for the input.
