Hey Josh,
thanks so much for the pictures. So they’ve obviously masked them up and just painted the outsides of the end plates.
I was going to remove my spoiler and disassemble it so I could paint the inside and outside of the end plates but I’m pretty sure the spoiler is glued together so pretty much impossible to take apart.
I may well do the same as on your car as it does give the same overall affect without all the grief of stripping it down!
And as you say it does look great!
Cheers.?
