I think applying Anything over any type of wax product is going to have to fall off sooner, because the Wax is the first product/foundation on the paint...
And any wax based product is never going to adhere like a true coating, etc... product

I will also never apply anything over a wax based product, because all the dirt, dust, etc., will Always stick to anything that is already somewhat "sticky"...
So now, you are rubbing something that may have dirt, etc., in it already, with another product on top of it...
