Howdy and welcome to airforums.com, Bill! We're pleased you decided to drop in,and I know you will find the answer to your question about cleaning.
I don't think that there's anything that will hide the fact that your clearcoat is peeling, but Walbernize is still a popular cleaner / shiner-upper for Airstreams.
However, I am positive you will see many more suggestions pretty quickly.
