Have they done a Scotchprint 1080 install before? I was able to fully wrap a spoiler that was urethane with no issues during install. I did use primer 94 only on the edges. The spoiler was not painted so it had smooth ready-to-paint surface and it was for an IS250. The adhesive is aggressive and forgiving. I have been surprised at the ability for the Scotchprint 1080 to install almost anywhere.
