Side Mirror Plastic
When I got a Right Side View Mirror for the car, it was in pretty bad shape. the rubber was torn up in a couple of places, leaving this white chips everywhere.
You can't really see it in this picture, but it was white chips everywhere (on the black plastic casing), and I just filled them in with a black marker. However, it was still rough, as you can see above, and the marker wore of quick. So I used Chassis Saver, and it worked like a charm. It's black, and smooth and you can not even tell.
Make sure you read the Chassis Saver Disclaimer, before working with it.
