If you're the sort of person who can't walk past a dirty car without writing "clean me" on it, you might want to up your game.
Russian artist Nikita Golubev has been turning other people's unwashed vehicles into works of art.
Using the name "ProBoyNick" he has drawn various designs in Moscow for the past two weeks and sharing his work online.
His first attempt picked up nearly 400 likes on Instagram.
He drew a smoking man's face on the back of the van and told his followers he was just "trying out some new techniques".
His most recent work scored over 2,000 with a process he calls #dirtpainting.
International attention on his work has now grown his Instagram followers to more than 10,000 people.
So far his work has included images of an octopus, a shark, a gorilla, an owl and a group of surfers.
It's a far cry from his previous pieces, which were more traditional sketches and water colours.
He creates his dirt paintings using his fingers and brushes.
