Issue with glowing objects

I'm trying to make glowing objects. Every other object should not glow. I checked out some older posts and followed instructions.

• Created a "Glow Layer"

• Glowing objects belong to "Glow Layer".

• "Glow Camera" renders Glow layer only (priority -2, Clear flags: Don't Clear), it is parented to Main Camera which is 3rd person controlled.

• Main camera belongs to Default Layer. ("Glow Layer" is disabled in Culling Mask list)

  Still, NOTHING glows. If I set the priority of "Glow Camera" to -1 (the same as the Main Camera's), obviously everything glows. How can I fix this?
