creating glow effect on one object only

Hi guys

I’m trying to create a glow effect user the compositor but I only want the glow to affect one particular object. Can anyone help please?

I know it can be done by having the objects on different layers but I’d like to have all the objects in the same layer – but just the one object glowing.

I think it can be done using mask ID but I’m not sure how to arrange the nodes. Can anyone help at all? I’m using the internal render engine by the way.

Thanks in advance

Here’s a very simple example of using obejct ids to isolate a particular object in the scene
