Obsessive detailing - what have you done?

[Proud owner]

I thought I'd start a thread to see some examples of what some may call obsessive or even pointless detailing, here's mine to kick it off.

When I recently took my rear bumper off to re-install one of the aftermarket parking sensors I had fitted that had come loose, I took the opportunity to thoroughly clean and polish the bumper's inside. It's something that will never be seen, I can't even use the excuse that it will prevent corrosion as its plastic, but at least I have the satisfaction of knowing that the whole of the bumper sparkles rather than just it's outside and looks as good as when it left the factory.

Looking forward to seeing your examples of what you've done to yours.
