Some waxes (e.g., #16) just seem better suited to machine application than do others (e.g., 476S). #16 is almost like it was *made* for application via machine, it does its "turn the paste wax liquid" thing even better by machine.
With #16, I use so little that despite using it on pretty big vehicles and applying rather frequently, a can lasts me over a *decade*. I end up using more 476S because going for an ultra-thin application doesn't seem worth the effort, which is sorta the opposite of how I use all my other LSPs.
FWIW, I do almost all my LSP-by-machine work with the Cyclo, not the PC. Only LSPs I always do by hand are KSG and UPP (and Souveran on the Jag).
Oh, and AFAIK the only reason to do the bare-hands method of application (or perhaps the latex-gloves method

) is because certain high-carnauba-content waxes supposedly need to be melted/softened by bodyheat lest they cause micromarring. I did the bare-hands thing with Souveran a few times just to see what it was like, and I didn't notice any benefit over using a foam applicator.
