The best thing I've ever used on an engine bay is tire spray-- it leaves an armor-all like shiny finish, but requires hardly any time since you just spray it on (engine bay is full of irregular surfaces which are hard to clean by hand or rag) and leave it. The problem with it getting dirty soon after doesn't go away, however.
AMEN! I've been using tire foam for years - fast and looks great!
