The 360 wand had a good 360 spray pattern but not a perfect pattern. You don't get enough volume to get complete coverage with one pass of the wand. Expect to do several passes to get complete coverage.

An other product you may want to consider is something like Fluid Film. The film that is sprayed on will creep into the seams and other tight places. The downside of them is that you will need to reapply them from time to time. This gentleman has done a lot of real world tests with these and other products.

I will say that this is subject is a rabbit hole that is full of folks with lots of strong opinions and at the end the question is do you want to completely disassemble the truck and epoxy coat everything before reassembling the truck? As that is where it ultimately leads to.

All of us have to decide on what process we have confidence in and that we can afford the time and money to make happen.
