Ahhhh, No. Unless you read something that I didn't find on their website.
ReJex's site actually says that their product CAN be applied over another product, even a carnuba wax, but the life expectancy of ReJex will be great decreased.
They go on to explain that once the wax breaks down (the base layer), it will wash away and take the ReJex with it. Makes total sense.
From the site: "RejeX can be used over existing wax, however, the duration of protection will be reduced as the softer underlying wax degrades comparatively quickly."
Since, I applied Sonax Net Shield (a long lasting sealant) and immediately applied ReJex, I've got a good, long lasting base coat of protection. The ReJex topper has the potential to cross-link with the Net Shield base as well. On the roof of the car, I only applied Net Shield, so I'm curious to see if the ReJex "topper" (I'll compare the hood, that has a ReJex topper....to the roof, which has only Net Shield) provides any extra protection/longevity.
In the worst case, the ReJex topper didn't adhere to the Net Shield, and it simply slid off the surface. But I don't think that happened, because the feel of the paint was dramatically different between the Net Shield only surface vs. the Net Shield with ReJex topper surface.
