Jim,
If you put something on the hose connections to make them slip off easier when you want them to, you run the risk of them slipping off when you don't want them to. First of all you don't remove rad hoses all that often, but if you are removing them to replace them, you can cut them with a utility knife. If you want to save them, Sears and others sell a neat tool I call a hook. You can use it to remove cotter pins and rad hoses. To remove heater hoses, etc, tool trucks carry plier like tools that push against the end of the hose and whatever you are removing it from. Both tools are hard to describe. You'd have to see them.
