Okay, gotcha. I was thinking that the filler was in the middle of the bumper, but it makes sense that you used it on the ends to level out the lines. Nice job.The filler is only on the ends getting the lines to match the body. I had to split the center of the bumper at the top and bottom to make it fit right. The bottom has a 1"x1/8" aluminum bar reinforcement riveted in. The top and bottom are both put back together with four layers of fiberglass and matting. Way too much work for a supposed to be finished part, but well worth it.
