I want to spray the items indicated in green, which are gold galvanised steel, So assume they are OK.
I also really want to spray the yellow denoted items, that are untreated iron. Some sort of “magneto affair” and the blue items are like laminated steel. Helped a friend with his Honda, that was unmaintained and the yellow items were rusted to hell and his is 5 years old (mine is now 13 years old) - so maintenance pays off . Previously I had just sprayed these with WD40, but that is a pain; as you have to unbolt the engine cover, and one bolt is a torqued cylinder head cover.
The question, is does it matter if it goes on the Red items i.e. the cylinder barrel and cylinder head and the lower casing. These are aluminium with steel bore liners.
I.e. will it bubble up and go horribly gunky?
apologies as I know its not per se a Mercedes issue, but you guys are the best engineering resource I know, and it might be pertinent to someone spraying their Mercedes engine bay
