Gerahead's 71 Dart

When I acquired my Dart, it did not have the splash shields that mount on the bottom side of the frame rails, just ahead of the lower control arms like in the image below.

I was able to source a couple from a donor, one really nice and the other ok. One was misshapen and has a couple of cuts/breaks in it. I was able to re-shape it with the careful application of hot air from my heat gun. These are kinda flexible and I am wondering if anyone knows what kind of a product would work to repair the cuts. The material is pretty thick so I could likely get away with v-cutting the edges and applying a bonding agent. Any ideas? L8r
