I have just noticed a very thin superfiscial scratch in my new car windshield. It is not noticable and you have to really search for it...but it's there. Is there an easy simple way to buff it out or some compound that I could use to get rid of it....or should I leave well enough alone? Or perhaps have it professionally removed. It is very insignificant but I know it's there. I am not sure how I got it and it may have been there when I bought it. Thanks.
