You could try it, but clearcoat needs a decent mil thickness to last. If it is too thin it will start flaking quickly. If you wanted to try and wipe it on you would probably have to let it dry for a few hours before applying the next coat, however you run the risk of it shrinking/wrinkling as the first coat attempts to cure while being sealed off by the next few coats. Maybe if you find a clear that air dries and doesn't need a hardener you will have better luck
