I have ordered some Espuma Activo to compare and will post up some results when I trial it on my RS.
All the pics shown are using only Magifoam and there was no pre-rinsing pre-soaking or APC etc applied... just MF straight onto car and left to dwell for approx 20-30 mins.
The car was then power rinsed thoroughly and pictures taken directly following rinse.
As a sidenote this was part of larger detail (that havent written up yet) and so I was following with a bucket wash. But I would say it removed >90 of the grime and dirt in a touchless manner, so how I look at it is that when I came to get the mitt on it, I have 90% less touching to do and 90% less filth and grime on the car and therefore 90% less risk of damage.
I will let the photos do the speaking

Side-Note - the owners did not require there plates being masked.

^^^^^ I think my neighbour was amazed when I told him, that yes, his was meant to be same colour as mine

































Thanks for looking
