As for tailgaters - we found by accident that just plain water works. The rear window washer on one of our Jeeps came loose and used to squirt water straight back. Just a coincidence but Marita found this out by cleaning the front screen while being tailgated, and then noticing in the mirror that the guy had dropped way back and was wiping his screen, too. Has the advantage that it would be difficult to prove you meant or could reasonably have foreseen any harm, and most people would probably not take as much offense as if you machine gun them :-D
I helped a friend of mine rig up the right front window squirter on his Acura to point to the right. He'd drive around squirting people on the sidewalk. Lots o' fun. Left it that way for years...
