The spoiler attaches by adhesive tape. It won’t attach to PPF?
If you don’t PPF the rear lid, you are going to wrap the edges around the spoiler?
It would stick to the PPF before a ceramic coating but would stick even better to the paint itself. Best to tuck the wrap around the spoiler edges.
I’ll be doing this with my car too. Leaving the trunk lid unwrapped until I get the spoiler. Hopefully by then though, there won’t be a shortage.
