I purchased the Wax-Oyl 2-gun starter kit from roversnorth.com. This kit includes the following:

I also purchased the following so that I had a wand to apply the hardwax with. I think this is very important when working in tight spots, which is most everywhere.

When I got the kit, I realized I would need to do considerable research to connect it to my compressed air source. RoversNorth was of no help, which surprised me. If I marketed this kit, I would include the following to keep people from reinventing the wheel every time.

I hope this helps you. You're welcome!!
