Recently I saw a Model Y (or maybe a 3) at a supercharger in California with a white roof. I am not sure how they did that? Possibly a wrap or a paint job? It looked smooth and perfect and my guess would be that it is a 2-part epoxy paint? Has anyone heard of that? Seems like it might be pretty effective in keeping the interior cool and it it looked pretty nice in my opinion. Could that be done with a wrap?
