Painting a boxtruck with only 2 braincells! halp!?

converting a box truck. Trying to reduce the heat footprint as much as possible. Never painted before. How many layers of how many products? The best I can tell I need an initial layer of anti-rust primer, a couple of layers of reflective paint, and something on top of that (car wax? weather paint??). Any recommendations of types, layers, and brands are greedily accepted.

TLDR: Painting box truck to reduce heat. How many layers, of which products, should I use?


I would use high gloss white exterior latex house paint, and roller with a long handle. Use as many coats as necessary to get uniform high gloss white.
