I'm guessing as its a glaze type product you should use it after the M-seal and before the butter wet wax,not sure about the layering, but doubt it would hurt to do a second coat of any of them for even coverange.
i'm planning to use is before m-seal, my question is, will the wet mirror and m-seal bond? cause i've browse other forum that says some glaze doesn't bond with sealant.
and anyone know about he curring time each of these products?
Wet Mirror isn't a glaze like a "real" glaze. I'm pretty sure you'd be safe using it before or after a sealent. If you'll be using a carnauba that should def go on top of WMF.
Here's a couple threads about WMF, might answer a few questions for you.
