hello everybody,

i am planning to wax my father's car this week and i need some advice.

I will be using kit wax which has been collecting dust for long time already.Is that brand good?Please recommend me some brand.
The paint of the car is black metallic and 6 months old.

My procedure is wash and wax only.Is clay bay or any other step necessary?

I also noticed there are some hairline swirl on the paint,can i get rid of them by waxing the car?

Also when is the time to polish the car if I wax the car monthly?

thanks lot for ur reply
ermm what else can i do to make the wax last longer,coz normally after few wash using water only the smoothness loss already.
