I added 3 layers of fiberglass mat on each end and now all I have to do is fit the center piece and a lot of bodywork and I will have a one piece bumper and valance!!
The center of the bumper had a flat section for a license plate that I built up with a lot of layers of fiberglass mat each piece getting smaller in the middle. The bumper looks pretty crude right now.
If the chin spoiler will actually help keep the nose down at speed it might be a worthy addition, if not, it's just something hanging out there just asking to get banged up.
