Did you try applying just by hand? As a way of troubleshooting?
This is a pure wax/sealant, by "pure" I mean there are no cleaners or abrasives, no harsh solvents. It should only be applied to a finish that is new, like new or as in your example, to a surface that has been compounded and polished to be like new.
When applying to a clean smooth surface by hand or machine, the goal then is to apply a thin layer. You do this my running a soft foam pad with the product on it to lay down a thin layer and this can be done with one or two passes over the area.
Once you have thin layer on the surface you move on to new territory.
You let the wax dry to a haze, about 15 minutes give or take a few minutes based on temp and humidity.
Then wipe it off to leave a slick, shiny surface.
The above will work by hand or machine.
