I assume that Imperial is a hard wax, Carnuba or similar. I find it interesting that Fine Woodworking magazine, years ago, did a test of the various woodworking waxes, and included car waxes in the tests. their conclusion is that wax is wax, and how it is thinned or carried makes no difference. The thing to pay attention to is how hard the wax is - beeswax being the softest and Carnuba being the hardest. A microscopically thin layer is one of the slipperest substances known to man.
Find a good hard wax in your hardware store, a floor wax or "Bowling Alley Wax" will be heavy in the hard waxes. It should do the job just as well. Saves money, too!
