I parked outside a renovation site today, when I come back I notice few small stones on my boot, and a stone impact mark on the roof, obviously its been dropped from the renovation site

the damage was down to the metal.. pretty bad, and make me question about bmw paint quality, because I can clearly see the paint coat is very very thin, just like a sheet of plastic covering the steel, anyway, now I need advice on what wax/polish to use to prevent further demage or oxidation on the wound

I have one coat of zaino on it, does it help if I put more coat on? or I need to have other heavy duty wax to prevent corrosion?

If it's down to the metal then no wax will prevent corosion. You'll need to touch up the area (with touch up paint).
