I used a heat gun and gradually heated the edge of the flare, then about 1/4" from the edge, I used a pair of pliers to grip the edge and bend them in toward the body panel. Before it cools and returns to its old form, "set the flare" shape you have bent inward by cooling it under cold running water. This process takes time to get it right, but it works. Trust me, I tried everything and ended up doing this. I am so glad I worked all of those hours to get these right, but I will NEVER take them off again, as they seem to lose their original form the long they are off of the car. This extra work is worth it.....do it right.
