If anyone is looking for a paint match to Model 3 Standard Range + Aero alloy wheels, I can recommend this from Amazon:
ANTHRACITE ALLOY WHEEL TOUCH UP KIT REPAIR KIT
madAUTO ANTHRACITE ALLOY WHEEL TOUCH UP KIT REPAIR KIT PAINT PEN BRUSH CURBING SCRATCH (JUST PAINT) : Amazon.co.uk: Automotive
I've uploaded a photo of my 'repair' to a scuffed wheel. Although it looks a bit rough in the picture, you actually have to look quite hard to find it and I'd say the paint is an almost perfect match.
Tip: I found that the brush supplied is a bit small plus paint builds up in the handle and 'blobbed' out so I used an old plastic lid to put a dollop of paint in then used a normal craft paint brush to apply it
