I was actually unable to find the colored reflectors (the ones on Ebay are advertised for E90s, but they look like they're for the E92s), so I bought color-matched spray paint instead.
It looks like this DIY is pretty involved and has a high risk of either: 1. damaging the reflector or 2. damaging the bumper.
I was wondering if anyone has painted the reflectors while they are still on the bumper by just masking off most of the front quarter area?
Or, if anyone has removed the old reflectors, prepped and painted them, and re-installed them?
Any help would be greatly appreciated!
