I haven't used Fusion but I have used a product called SEM when I restored my plastic door panels and it's held up well for nearly 4 years now. It may be available locally but I purchased from yourautotrim.com .
I also used SEM Vinyl Prep before I painted. The stuff's not cheap but I've been very please with it.
