ILD: hehe madali kc gamitin ang Mother's.. anyway, daming factors kasi.. you can try to spritz some QD on the car's surface and on the pad to prep it. this makes wax application easier. BTW, if the car is properly prepped, mas madali yung application din.
patopig: Nope..try to get the Cal Duster and use it before QD. However, if its really dirty and may dirt "film" na on your ride, Using a QD in this situation can be really risky. What some people do is that they QD after washing the car. Lubricates enough and lessens marring during the drying process too.
