It is possible. The stuff I used was for removing graffiti, spray paint, etc. It is really strong citric acid. If you have a spare piece I would give it a try.
i wonder if this would work on plastic chrome? im looking at a car that had all the chrome painted black on the mouldings. and im worried if i spray anything on it it will remove the chrome color as well?
I would try to do a practice piece first that is hidden from the eye. Try not to use anything that is super abrasive to scrub. Maybe something like a very fine piece of steel wool.
