Modern thermoplastic resins can be repaired to a state that is just as strong as the original factory mold. I was initially skeptical about fixing a tear, but I wanted to avoid the high cost of a brand new OEM part. While searching for a body shop that specialized in advanced plastic reconstruction, I came across a useful directory for our local area. The platform at https://autobodylab.com/ allowed me to look at the equipment these shops actually have in their bays. They used a hot-staple reinforcement technique on the back of the panel to ensure the split could never open up again. The finish is so smooth that I can't even point out where the original damage was located. It saved me hundreds of dollars compared to buying a new bumper from the dealership
