I figured the amp dosnt get that hot, i am not worried about the paint cooking. what is the advantage to powdercoating rather than automotive paints??
the color i picked is identical to the car, i cannot achieve that with powder.
has anyone eles used this type of paint on their equipment??
Don't worry, paint will be fine.
The main advantage of powder in this sort of application is it's ability to get into the depths of the heatsink 'grooves' better. 
Highly simplified - paint goes where you point the gun, but due to the electrostatic charge used powder 'wraps around' complicated shapes.
Providing your paintshop know what they're doing you should be fine. I'd be using a mini-gun at very low pressure to reduce blow back (the air coming from the gun creates a high pressure area between the fins so the paint simply blows back out).
With something like that I think you'd be fine, but with the deeper finely spaced fins on for instance an M series, you'd struggle with paint, and powder would be almost a necessity (unless you're as good as me, lol  

 )
