How do I deal with hairline scratches?? I found some today on the doors and I believe I can kinda feel it. I have Menzerna twins, AIO and some old TW Color Back (seems to be the only products I have that can do something with scratches and other imperfection). It's white so does that mean it when through the clear?? If a polish doesn't work do I have to use a touch up paint, wet sand it, compound it etc, etc.......???
