Is pepper spray the same as mace ? If not, what's better? >>
There are three basic chemical compounds used in self defense sprays:
· CS (Orthoclorobenzalmalonitrile)
· CN (Alphachloroacetaphenone)
· OC or Pepper (Oleoresin Capsicum)
OC is the newest of the three, by far the most effective, and the best one you should consider for self defense use. Pepper spray effects everyone differently but it is by far the most effective
Pepper Spray Effects
CS and CN are irritants to membrane tissues. They cause stinging pain and te aring, and take from 5 to 30 seconds to be effective. In cases of persons who are drunk, on drugs, suffering a psychotic episode, or otherwise cannot feel pain, there may be no effect at all, For years the field experiences of police officers has been riddled with accounts of total failure of CN and CS products when used as a self defense spray.
There is no basic difference between mace and pepper spray as Mace is a brand name, not a type.
That being said, there are different mediums to expel the agent. Foggers, streamers, pellets, grenades, and foams. Now pellets and grenades are out of your reach (for the most part), but the other three are commonly available if legal in your state. More information to follow at the end.

you have to have a permit for mace. i'm not sure about pepper spray >>
All legal situations like this are on a state by state, city by city basis. Rules vary nationwide. If you don't know how to proceed getting info, PM me and I'll be happy to provide the appropriate statutes, or at least links to where you should continue your search.

Either one will down your target in seconds. >>
BS. Everyone reacts differently to all chemical agents. While strong OC is widely effective, it is not absolute. Many people are not affected at all, while others have minimul reaction, and some are allergic in a manor that causes death should they be sprayed (very rare btw). Some people are immune to them all, some are only immune to one or two types...it totally varies. Overall stong OC (10% or better if allowed by law) is the MOST effective, but don't rely on it totally. No tool will ever replace your brain for effectiveness in combat.

It sizzles on pavement. >>
Not that I've ever seen. Maybe the pavement was hot, or the propellent reacted, but it's mostly inert. In fact, when it was originally pure pepper extract in the sprays, many law enforcement people used to season their food with it.
Having said ALL THAT, I'll give you my advice (2 yrs military, 8-10 yrs security, 2-3 yrs assiting (residing/working) leo's).
1. Make absolutely CERTAIN that you are WILLING to use it. If you aren't sure you can spray someone, knowing it may cause their death or have no effect and get them mad enough to kill you, then you have no business carrying.
2. Get training. Take a law enforcement sponsored, or professional course in the use of chemical sprays. Not only will it train you to use it properly, it will teach you when NOT to use it, which, in our age of civil liability, may be even more important.
3. Use your mind first. It's far better to not need the spray, than to know how to use it. Your mind is your greatest weapon.
4. Take additional training. Chem sprays are something, but they aren't everything. Know how to fight unarmed, learn additional weapons (a gun if you're comfortable and legal), take street safety courses. Safety isn't as easy as everyone thinks, trust me.
My own experience with chemical weapons is to learn the laws first. Then go with a very strong oc foam (at least mk iii, or mk iv size) if it is legal for you.
Here's an example. In all my exposure it's the only type that affects me to any degree, and it has the fewest downsides. Definately get training in the proper use of whatever you end up with, or it'll be more of a liability than an asset. Spraying yourself won't help you out much
