Are you using the glaze to hide swirls? Just wondering as if you just polished to remove everything then you'll not need the glaze. Remember that glazes have a VERY short lifespan/durability. They have their uses for sure, but more for show cars and such that don't see the elements.
Two things come to mind. WG doesn't have any abrasives AT ALL. While Opti-Seal, while being advertised as a sealant actually does. I'd put Opti-Coat over OS, but that's about it. Nothing wrong with a sealer, but OS is more of a polish and sealer. I wouldn't put it over a glaze, even though it's said that it'll migrate beneath some materials.

I'd say forgo the glaze (unless you either NEED it to hide swirls and just want to keep doing it every couple of weeks) and go for the WGDGLS.
