Painting Speaker Grilles and Cones?

[Rattlesnake]

Hey guys!

I've had my Sony surround sound speakers for a while now. They all all Black except for their front grilles which are grayish and if I take off the grilles the Cones of the speakers are yellow but the dust caps are black.

I want to make them all black. So is there any spray paint to paint the grilles which will not worn out? If not then is there any spray paint for cones which will not mess up the cones?

I need to know both methods and how many coats should I apply for each method.


Thanks guys!
