It's not recommended using Sonus Acrylic spritz over a carnauba topper like S100. The spritz should only be used on top of SG before any carnauba that's applied after. However Sonus now has a carnauba spritz for maintaining S100 just for someone like you who wants to spruce up between waxing.
I would say if you were going to stop at the SG, then Sonus is for you, but with that additional carnuaba layer, it's not really the optimum product. You'd want to use a carnuaba based QD like EFCP (my personal favorite) or one of many others...
