I just posted this in another thread.

To elaborate, Titanium dioxide radiates heat in all but direct sunlight. Recent experiments with [IIRC] calcium chlorate show it can radiate heat even in direct sunlight. So I misspoke in the other thread. hee's the homework: www.youtube.com/results?search_query=paint+cools+in+sunlight


Youtube is full of videos on how to paint cars with Rustoleum

Rust-Oleum® Stops Rust® Gloss Protective Enamel Metal Paint Masstone Tint Base - 1 qt.
Model Number: 7507502 Menards ® SKU: 5515008


edit: Maybe that's backwards? You want to promote heat gain? I'll revert to my default suggestion -- Black Plastidip.
