Or some Si02 spray product as a topper/booster?

It is a different way of looking at detailing products, and what works better, what is compatible with what, etc. I may give the CanCoat a whirl on my car once I get it polished and see how it holds up for the warm part of the year, then switch to the traditional sealant/wax before it gets cold once it starts to break down. May still do the Essence on my wife's car
