The best wood preservative is good wood. Black locust, cedar, etc.... But seeing as that's not the route you took, there used to to be a product called wood duck. It's amazing. One application is still holding up on a 10yr old deck. Heck they may not even make it anymore? I will make a suggestion for whatever you decide to use, Wagner electric sprayers work well and if you buy a properly sized inverter, you can power the sprayer off the truck and haul your materials at the same time.
