How do you apply the wax to your pads? I used an old plastic knife and put a little over a tablespoon of paste wax on it. Whenever I first use it on the car there is always too much wax where it is first applied. Should I turn it on for a few seconds before using it to let the excess wax fly off? It wouldn't be a big deal, but it is really hard to get off the parts where there is excess wax.
