Polishes and waxes

[project 064]

Zaino & Pinnacle are my two choices for my cars.
Zaino Products are very hard to get in W.A., most detailer's have their own "special brew" that they concoct with chemical engineers, & are very reluctant to sell you a bottle of their "special brew"
I know of 3 detailer's in Perth, that are in talks with chemical companies, trying to establish their "special brew" as the market leader.
Is this a cost effective way of doing business? Why not let Zaino, or Dodo, or Mezerna do all the testing & development?
