Before you suggest chromecarletters.com those don’t really match the font of the brand.
I’d be happy to learn about any sources for this, but specifically I’m looking for the font used on the back of a Toyota RAV4 which seems to be consistent for the past 15 or so model years. It’d be very cool if someone sold the OEM lettering.
I’ve never actually successfully made anything shiny with that type of “chrome” spray paint. But they can give it a shot.
You’re right that most car badges are plastic anyway, covered with a thin veneer of that flaky chrome effect stuff. I have no idea if it’s actually chrome or just some kind of shiny plastic, a hot-dip process, some kind of PVD or sputtering, or what.
