Whatever you do don't wipe over any plastic trim with acetone or any other solvent because it will probably end up dissolving the plastic trim in the process. If there is not too much trim and it can be easily removed, you could try spraying with a matching colour to the one you want. It is usually OK to use normal car enamel in a spray can but you will have to use plastic trim primer first, then give it several light coats of the desired colour to finish it off. You could always try spraying a section on the back of the trim first to make sure it doesn't have a reaction with the spray paint.
