Depends on the wax itself. After sometime, normal wax will usually lose it's effect and get washed away. Common cheapo wax lasts anywhere between 1-3 months, better ones (meguiar's, etc) may last u up to a year.

so ish 2 to 3 weeks or 1 month wo, confirm if wax liao ranining will have no watermark har

Water beading decrease but the wax still there ma. Unlike turtle wax and all that where the wax layer fall off like a leper's skin. Patch by patch.
Yeah. Or u can try us.

Ahh, also depends on how/where u park ur car, rite? If everyday exposed to sun & rain, wont take long for even the best wax to lose its' effects.

Bear you some mean something like this?
