Man thats not so bad... who ever molded it should have used different materials, but thats even hard for me to say that. There are so many products out there. I use a product called fibral by (upol). This stuff is incredible. After molding I try to break my pieces, and the end result is they don't break. I also use this to mold fiberglass to urathane, holds like a charm. From what I can tell easy fix. First you will have to clean up broke edges make them bigger. Then put them back in place using some kind of shim to hold the piece in correct proportion. And fiberglass them back together. 9x out of 10 that bumper will be stronger where it was fixed so I would rein force more areas on back side. For the price of that kit I don't know why they don't have a full front it would be more drivable then. Molding is nice but it's not really for cars you drive. If you have any questions PM me.
