That's not a true ceramic. I would use the Collinite first. That Turtle wax is just for a quick touch up shine.
that's not accurate. watch the many youtube reviews by Professional detailers...this stuff is the real deal. It's not just a spray on, quick shine. It's a spray on quick shine that gives you months of protection, gloss and beading. I've used it, I'm a believer, and I have a cabinet full of various waxes, polishes and sealants that I've used through the years. This type of product is a game changer.
Put the new Griots spray on ceramic coating in the same category..great stuff.
