Don't use a screen on the port because it will be too restrictive.
Use a can of black spray paint and lightly mist the insulation in the area behind the port. Don't saturate it, or the fibers will become stiff and lose effectiveness. Test it with your hand after it's dry and make sure it's still the same consistency as the untreated fibers. I've done this before and it works very well.
