Yes, Nu Finish Car Polish does contain silicone. Car polishes and waxes that contain silicone are not bad for your car. In fact, all car polishes actually contain silicone, if only for lubricity. Today’s silicone emulsions found in car polishes will not cause “fish eyes,” which are small circular craters that appear in the finish of new applications of paint. Applying fresh paint to the surface of your car that was recently waxed or polished may cause fish eyes in the paint if the proper steps weren’t taken to remove the silicone or wax prior to repainting the car. But fish eyes don’t appear in your paint’s surface if you are polishing a dry, painted surface.
