Since folks are downvoting this comment, here's what Gemini told me, and which sounded reasonable to me. Let me know if something sounds wrong: Paint thickness: 120 microns (0.00012 meters) Typical car surface area: Assuming a medium-sized sedan, we can estimate this to be around 15 square meters (161.46 square feet). Paint density: This varies based on the type of paint, but we'll use an average value of 1.2 g/cm³ (1200 kg/m³) as a starting point. Volume = thickness * surface area = 0.00012 m * 15 m² = 0.0018 m³ Weight = density * volume = 1200 kg/m³ * 0.0018 m³ = 2.16 kg ChatGPT was similar but chose 1.3 g/cm³ as the paint density.
