I dunno about that, seems like BS. Black attracts heat, don't know about dissipating it

Paint is an insulator. You would need a special coating that transfers heat better than the bare aluminum. Typical paint will not do this, but the previously mentioned swain coating may.

Yeah paint is typically an insulator. There may be a special material that works.



LOL, almost like saying if you paint your windshield you would be able to see better at night.
