Hey guys. This is my first non-introduction post so fingers crossed it's not too noobish 
I wanted to know if there were any potential problems in layering a carnauba over a sealant. I've read that a lot of people love the glow of a carnauba but also want the long lasting protection of a sealant, so they layer one over the other.
If this is such a good idea, why do companies like Zymol (personal feelings aside) always suggest to go straight from a paint cleaner like HD Cleanse (sorry if the name isn't 100% correct) to a wax, rather than a sealant in between?
I don't have any professional detailing experience or enough general experience in experimenting with various products to know the potential downfalls associated with this practice.
Thanks in advance for any advice.
