How do I maintain Single Stage Acrylic enamel?

not a paint expert, but I've been told you shouldn't get too aggressive with cleaner waxes and rubbing compounds with acrylic enamel paint. I've heard that the surface is relatively hard, but that surface is thin and if you wear through it, and expose the soft underneath it will deteriorate rather quickly. I tend to believe that is the case, because I was using Vista cleaner/ wax on my '76 Dodge pickup, and that's exactly what happened.
