Mate,
you need to have a good read on the forums, particularly:
If you’re a true newbie, then start small and work up with a single product. The general advice on here is try Ammo first, then combine with a spray or two of a social such as Instant Shine or Instant Openness. What you use all depends on the effect you’re searching for.
However, please do not just spray willy-nilly - you may well end up with an effect you definitely do not want. Like someone belting you!
