Hi everybody. I just purchased the Zaino ultimate kit and, bought some z8, and some z-pc to take out the scratches on my car. I have been searching through this site as to how to apply and, what to start with first. It seems everybody has a different approach. So my question is what do I start with first? I know the first two steps. Wash,clay. Then what do I do next? I would like to use the Z-pc since I bought. Also my car is a 2001 Lexus GS 300(platinum/silver) Also have some oxidization on the headlamps, what Zaino products would work best for this? I will be doin everything by hand. Thank you.
