Write On® products are formulated for outdoor use and will stay on well in many conditions.  If you have trouble erasing an old message, use any dry erase board cleaner, rubbing alcohol or almost any household cleaner. Don't have any of those with you?  No worries, just take any color dry erase marker and literally trace over the old message and then use the eraser to wipe away both the new AND old marks!  The fresh ink will loosen the old message so it will wipe away like you just wrote it!

 

If you need to remove a Write On® sticker from your car for any reason just pry up a corner with your finger and then peel the sticker off.  Watch the video below to see how easily and cleanly it peels off!  The sticker in the video was on a car for 4 months in both Florida sun and Virginia snow and still came off with no effort!
