Car Window Markers for Glass Washable - Temporary Car Window Paint for Most Surfaces Tire, Mirror, Windshield - Car Chalk Auto Marker, Removable Autowriter, Rain Safe (Black, 15mm Jumbo Tip)

I am kicking myself for not reading the other reviews more carefully. I tested this on a small section of my white car , it washed off easily. I went ahead and wrote my message on the car, it was on there for a week and when I tried to wipe it , over and over , with both water and then a weak water / dishwater soap mix it still has left a faint residue , similar to the photos in other reviews . This is a disaster , I may need to get those areas repainted !! Beware when using on white.

These pens were awful! We ordered to mark up our car for her graduation parade and the color ran all the way down my car.
