What did you use to clean the engine BEFORE you applied Sonus Motor Kote?
I can spend back-breaking hours over an open engine compartment, trying clean off the engine itself and its components, the surrounding bay, and under the hood itself. I try not to induce too much water into an engine compartment, so I am very reluctant to spray pressurized water into an engine for fear of shorting out the many prevalent electrical and computer components in a modern engine compartment. My methodology is more damp clean/brush and wipe rinse, which is very tedious, but effective. I prefer Optimum`s Power Clean for a cleaning degreaser and Optimum No-Rinse for the cleaner soap for the sheet metal parts. And, yes, I resort to using cotton swabs (Q-Tips) for visible exposed areas, like recessed bolt/screw holes or intake manifold gallies.
Nice, clean-looking Mini-cooper engine compartment, by the way!! Thanks for the different bottle with better/finer sprayer nozzle suggestion.
