FOAM cleaning on coated vehicles

[mobiledynamics]

All 3 of our cars have coatings so it's tough to A/B...

Bearing the hydrophobicness of said products, for pre-foam dwelling/pre rinsing applications, do you find

- using less product on panels since less sticks onto it
- same level of product

I ordered up some TFR based foam from overseas....for cleaning. Just wondering how much or how little this affects things in the overall scheme of cleaning

Example. The bumper/rear of our SUV needs mechanical agitation more than the rest of the car. Just due to aerodynamics, dual exhausts, etc, etc. It's almost as grimy as the lower rockers.
I'm always looking to improve on making the wash process touchless

The foam gun I use with non diluted soap I fill it with on the max soap setting still doesn't stick to the CQ enough IMO. Pressure washer blows off most of the dirt so less likely to add swirls when washing.
