Spoiler gone!
What an absolute pain in the rear that was!
The silicon sealant around the perimeter was nuclear blast resistant! I tried everything. Tar remover, numerous solvent cleaners.
I also tried one of those caramel wheels that you stick on a drill, that also struggled but I wussed out anyway as it was just crying out for me to burn through the paint.
Petrol and much scraping with an old credit card eventually removed it. The process took me about 6 hours!
A 2 stage machine polish and it now looks like new.
The spoiler will be in the for sale section soon enough. I think these were a BMW option from new??
It's very nice. Deep glossy carbon 3k and fits perfectly, but just not for my taste.
