Light scratching and Krylon paint worked for trim in past for me as well. Painting the glass for a permanent background is another thing. Make sure glass is clean... then clean again with rubbing alcohol. Use only a high quality acrylic enamel paint. anything oil base will peel off like rubber. I do coats over the course of many days and the more coats the darker it gets. I use a very fine sponge roller to accomplish this brushes leave marks... oh, and painters tape cut with razor blades to protect what you dont want painted! I prefer the painted on backs as they seem to make tank "glow". Whereas a tape on background is rather dull... unless you do the crinkled aluminum foil job.. but thats another animal!
