Someone keyed my Verna from front to the back

Was dusting my car when I noticed a huge line from the front door to the taillights. Just got her washed yesterday and it was sparkling. Today I find out that this has happened. Couldn't happen in my society as it's been more than a year and nobody plays near my car since it's on first level although my family is telling me someone did it outside. What is the best solution to fix this? I'm tired of living in constant fear of something happening to my car man it's tiring to even step out cause people are complete asshats
