Hi guys, I am quite confuse after going through the forum. Need someone to enlighten me. What is sealant? Is it same as wax? Whats AIO? Which 1 should i use for my car?

 

What i have been doing for my white car is wash and apply those normal type of wax i can get from petrol kiosk only. Because of the colour of my car, it will be very tough to wash if the lay of wax is gone. Any reccomendation for me?
