Depends on the glaze. If you use DWG or CG EZ Creme then you can glaze before sealing. If you have DWG, though, I would seal, glaze, then nuba just to make sure my sealant sticks but CG EZ Creme has slight cleaning abilities so I would use
that right after polishing.
If you're using almost any other glaze (like 3M IHG or
Meg's #7) then you have to wait to glaze after the sealant.
