Zaino was already available in KL a couple of years back brought in by one of the workshops in Subang but not the full range. I've been using them for a very long time before they even landed in KL. I have been buying this stuff direct from Zaino Bros all this while. Zaino has always been the choice of showcars (apart from Pinnacle which some still choose) even before they had the ZFX Accelerator (which was a b1tch to do before this as you have to leave your car for days to finish up before you can even drive it).
Yes they are easy to use but there is a regime that you must follow and you will need to spend a lot of time doing it even with the ZFX Accelerator. It will be confusing and sound tedious in the very beginning. Once you get the hang of it, it will be a breeze. But bear one thing in mind, Zaino is not a magic bullet. In order to get the ultimate mirror finish, 3 pre-requisites you must have:-
1) The paint itself and the painter's skill (if its refinished)
2) Dark colored finishing
3) The paint surface itself is prepped properly (wet sand, dry sand, flattening, compounding-heavy to light, glazing-heavy to light)
The paint will be the one that gives out the shine and reflection so how perfect is the finale will depend 95% on this step, Zaino just gives it the edge. By applying Zaino no matter how many layers onto a surface which is dull and not prepped properly, the outcome will not be like mine even though it is black/dark colored.
Once you have Zaino'ed your car, maintainence is a breeze. All you have to do is wash down every week and just do a QD with either Z6 or Z8 whichever you choose. And no, you do not have to use the Z7 shampoo. You can use other shampoos as long as the shampoo does not strip of the sealant nor contain any waxes (most shampoos don't apart from dishwashing liquids). As for how water repellant it is, the only other product that can even come close to Zaino is Fuso Coat. The effect will stay there for a couple of months even under our harsh weather condition BUT you must QD with at least Z6 after every wash. Z6 will re-vitalize the coating. Washing is also a breeze, all it take for me to wipe down my car after washing is the Water Magnet and 3 mins max.
