    I used high temp barbeque grill paint. It's flat black, and you don't need to clean the surface at all...this paint covers everything....metal, plastic, bugs and all.

    I would think that any kind of coating you put on radiator fins would inhibit heat transfer.

    Any layer of anything against that radiator will screw up the heat transfer unless you find something from a manufacturer that is paint for radiator which helps with heat transfer i would paint it IMHO

    are you saying this form experience or talking out of your ass?
    I've had my radiator painted for over a year, and have never had any sort of issue

    no need for a hi-temp paint. next time you drive somewhere, as soon as you park, feel the radiator....if the fins are hot...you've got bigger problems.

    i used hi temp simply because it was the only flat black paint i had at the time, but regular black paint should work....like others said, just keep it thin.

    I just wanted to use grill paint because it covers EVERYTHING. The high temperature resistance was simply an added bonus.

    What you guys are painting is the a/c condenser not the radiator.

    Working quite a bit in the HVAC field and having lots of experience I promise you that it's true. If you painted your radiator and didn't notice a difference it's because the system is not overloaded (excessively hot) but when you need the extra cooling capacity the paint will inhibit this. Then you'll wish you hadn't done it.
