Insulater Wax is great, easy to use ,doesent dry white ,high gloss ,lasts a very long time, beads like crazy. You dont have to layer anything over it , you can layer Insulator over other stuff. Insulator is a straight wax.
Spilchy, I was just waiting for you to appear on this thread.
I honestly don't know why more Autopians don't try Collinite. I've only tried their "Marque D' Elegance" product but it was better than P21S for shine and nearly as good as Souveran. And it has awesome durability.
That said, I've never tried the Insulator wax. I hope to soon.
