Occasionally when I'm learning how to make something new I read up on the product and when I started painting a lot of things, I learned how modern paints are incredible, mainly because the car manufacturers drove the technology over 50+ years and they continue to use paint for cars today. I think it would be crazy to ignore that and choose to make a stainless car/truck/abomination but to be frank, I think this vehicle was built more on a whim based on something Elon said and then told people to do, and it will be discontinued as impractical and unreliable within 1 or 2 model years.
