I tried to clean off a blob of white paint on the rear side marker light’s lens. I guessed it was latex. It wouldn’t come off with fingernail or plastic scraper. I didn’t want to use a metal scraper so I painted on a bit of Citristrip, figuring it wouldn’t harm plastic. I was wrong. It seems to have stripped off most of the orange-ness of that part of the lens. I suspect it’s just as functional as a rear side marker, so I won’t replace it, but if there’s a fix I’d like to try it.
