Acrylic rear hatch

Rear engine cover - I believe these are made from Acrylic? Do they have a factory tint or something on them? My glass/acrylic is flaking and needs refurbing. Is this just a matter of removing the old film and reapplying a new tint?

Thanks in advance.

I believe they’re polycarbonate rather than acrylic, and the tint is in the scratch coat/lacquer rather than being a film. Quite difficult to repair :frowning: I’m sure someone must’ve done it before, but can only find this thread from a while back: https://www.exiges.com/viewtopic.php?p=225845
Is it definitely the surface that’s flaking and not the inner layers delaminating?
