William, I use paraffin wax with a little black shoe polish blended in, once this is melted and homogenous I incorporate vegetable oil (2:1 ratio oil to wax), this allows me to put it in a spray gun for application.
I use this set up for speed and ease but when finished I have to use near boiling
water through the gun to clean it out so it will work the next time.
My spray gun for wax is a standard automotive type that I got from harbor freight, the cheapest they have, no need for a high dollar unit.
