It's probably not something you notice, but F1 cars a covered in paint. Without it there would be not liveries. While I can't tell you exactly what's in it, I can tell you that it has been described as a Paraffin-based light solution. Linolic Acid has also supposedly Anyway, I found out that the paint on an F1 car weighs as little as 1 kilo. It also adds no significant amount of drag or negative effects to the car, beyond weight, the paint really does nothing bad for the car. There is also another type of paint, aero-sensitive (flo-viz) paint.
Developed by Mclaren in 2010, this special type of paint took testing aerodynamics to a whole new level of efficiency. Its official name is airflow visualization paint, but no one has time to say that so it's flow-viz for short. It was originally just used in the wind tunnel, but was brought out to increase the amount of aero testing Mclaren could efficiently do. See, the issue was that they could use sensors, but the sensors would have an effect on the aerodynamics of the car. If you've ever seen a CFD gif or image then you know basically what aero paint shows. It streaks in neon blue or green when under pressure from air so teams can asses the aerodynamic efficiency of their front wings, rear wings, or diffusers. Theoretically, there should be long, clean strokes on the car (much like the Red Bull above).
