Good stuff. You can't go wrong with either clay bar kit. The spray bottle is detail spray and not a wax. It is used to lubricate the surface when using clay. You can also use it to remove dust and finger prints.
Ultimate wax is not for everyone. It sounds like something was wrong in the application. Ultimate wax has to applied very thin.
Ultimate wax is meguiar's current longest lasting wax. NXT 2.0 is right behind it. I'm a fan of both. I actually use the professional version of NXT 2.0 called M21 synthetic sealant 2.0. With the color of your car I would do 1 coat of NXT or UW and follow that with a coat of gold class carnauba. The carnauba will give the dark paint a nice warm glow where as the synthetic wax will give you the wet look.
Good info
Remember beading doesn't mean protection. When water beads on unwaxed paint does that mean it is preotected? Ulitmate wax sheets water.
You should go over on meguiars online. They have started there Thursday night detailing classes. They are in Irvine. You are not that far. Let me know if you need some help or if you need some helpful tips.
You have the process correct. You can wax by DA or by hand. That is your choice. Remember you want to apply either ultimate wax or NXT 2.0 thin.
A grit guard is in each bucket is a good idea and good practice.
Good tip.
Good stuff. I recommend you get a pad conditioning pad and clean your pads after you work on a panel. A panel for reference being a fender. For larger areas like the hood or roof divide it up into smaller workable sections.
You also want to do this in the shade. You don't want the surface to be hot when you work.
