Great job!

But same concern here, using UC on a monthly basis might really lessen the clear coat sooner than necessary, and if it would be just for removal of stains a choice of chemical and abrasive cleaners and lesser aggressive polish might be a better option, if its just for spot removal of stains most of the time abrasives are not needed and considered too much albeit effective in doing the job, one other concern would be if its used for spot removal then you might end up with uneven clear coat level that might result to certain area's experiencing clear coat failure sooner, rotary setting on 3.5 is also a bit fast since those speeds are meant for heavy defect removal already, i just hope you are using a medium to least cut pad for the job, but then again as they say the results speak for themselves and whatever works for you works

BTW if you experience stains on those area's try to use a mild solvent cleaner and pre-soak the vehicle, usually does a great job of removing stains as well

but bottomline with those results great job!
