The old trope of media blast warping is just that -- old. Good media blasting companies know what they're doing. They used "Dirty 30" grit on the bottom of the car to get off the undercoat but all the visible body panels are done with plastic beads to prevent heat build up. Besides, that valance is welded to the core support so no amount of blasting heat would be able to cause those wrinkles. Perhaps there was an accident and poor repair but even that seems unlikely given how straight the trailing edge is. Prior accident damage was clearly visible on right front corner (subsequently metal finished much closer) but a blasted/stripped car really exposes all prior work and the lower valance just doesn't look like accident damage to me. Maybe mine is uniquely wrinkled. Just seems unlikely.

We cleaned that up quite a bit but it was all up fairly high:

I can easily shoot pictures that make it look straight (see below). You really have to shoot from the side on a smooth panel to know for sure. Hard to say how straight the the image above from
@mulberryworks is with that textured finish. From the shadows it looks like there are wrinkles near the trailing edge to me.
