Filler/glaze over epoxy wait time
I sprayed two coats of epoxy primer and need to know what the wait time is before applying filler and/or glaze. Should the epoxy be sanded before applying filler and/or glaze if within the epoxy recoat time?

You did not say what brand of Epoxy you used. I use SPI, and I wait until the next day before applying filler. You don't need to sand the epoxy before the filler with that. You might want to check the tech sheet for that brand.

I used PPG MP170 2 part Epoxy. The tech sheet does not have any specifics on filler, just recoat time (3 days).

Most epoxies will let you spread filler over them after an hour under normal temperatures (75+) and anything over the hour mark is great with the very best time being letting set over night.
If it were me I would love to see a four hour wait anyways. Time is on YOUR side!

So I do not need to do any sanding as long as I am within the recoat window (72 hours)?

NO but if that bothers you just hand scuff with 180.
