My car is almost a year old and I've applied Zaino twice by hand. Does the Porter Cable do a better job applying Zaino or is it used more for polishing.

Who hear applies a coat of wax over top Zaino? I have some PS21 but have not used it over the Zaino. Zaino is all I use currently (Z5/Z2/Z6)

My car has some very minor scratches that are beginning to appear. The car is Black and I'm wondering if I should polish it or wait another year. How often do most of you do a full polish on your car to remove minor scratching?

 

You can use an orbital to put the zaino on but it isn't recommended because you will need to use a lot more zaino than if you were to do it by hand. Last time I zainoed it I used 3m Finesse it to polish the paint to a bright shine, then put the Zaino over it.
