Those are some great tips. Clearly the biggest one people should keep in mind is to always be polite. If you are an ass, it just gets them more fired up and you are more likely to get hassled and arrested. I am also a firm believer in never giving consent, but it really depends on the cop and your hiding spot.

Also for the record, NOTHING will beat a dog's nose except time. The smell of cannabis eventually permeates ANYTHING it is put in, regardless of what you try to put around it, and over time, the cannabis will create a "scent cone" around whatever is holding it that the dogs can smell. You beat the dog's nose because the smell didn't have time to permeate whatever you were holding the cannabis in, not because of any product you put on or around it. Dogs can even smell cannabis through a gas tank with gas in it because of the scent cone around it if the cannabis sits in the tank long enough and the smell is allowed to permeate. Watch Barry Cooper's Never Get Busted Again, he explains how the dog's scent works in great detail and how to go about getting around it, and its very informative. Nothing can beat a dog's nose except planning and time.
