Never tried rubbing it in, but I do press scent from one wrist to another. Kinda like spreading the scent around without overdosing on a spray here, a spray there. I also do strategic half-sprays when possible (not always possible though - some sprays seem to work on an all-or-nothing principle and you have no control over how much spray you get.)
A good place to spray is in the crooks of the elbows.
The back of the knees is also another spot, though not usually the most obvious place to spray. Particularly effective on scents with a lot of siliage/very strong scents. (i.e. M7, Quorum, Pasha)
Although it is usually a fantastic spot for spraying a scent, the back of the neck might not be the best spot for a scent which is long-lasting/strong. I recently did this with Boss #1 and it was a bit cloying. I would expect this would be lethal with a scent like M7.
