I work at an auto store, have tried a few different things.
Armor-All sent us all free trial containers of their new extreme shield wax. I put it on and was disappointed. Not nice at all compared to the Meguiars NXT Tech Wax.
It's the only thing I recommend. Clay bar + that is the glassiest smooth car ever
I use it on my car and bike after I clay bar it and hit it with a eagle one synthetic polish which really makes the color pop, especially my carbon fiber exhaust and hanger on my bike.
