I like to give a really good clean, don't have snow foam but I'd like too, Generally don't take parts off but will be as thorough as possible, making sure to get in the door jams and behind the fuel filler, and making sure I go right under the sill and in the arches of the car too, love experimenting with different polishes, clays and waxes to see what works well. Don't have the budget for the really fancy stuff (have you seen how expensive polish can be??), so I guess on a scale of 1 to 10 I'd be about 7?
