Epoxy>bondo>featherfill schedule?

[Alex V.]

In the process of painting a friend's '89 E150, the prep took me a lot longer than I suspected and I'm looking to make time where I can. The Eastwood epoxy we're using as a first layer has a recoat time of 30-60 minutes and a cure time of 5 days. It's going to need a good bit of bondo work to fill out some customizations - if I'm as precise as possible with the bondo is there any reason I can't apply it and the first coat of featherfill during the epoxy's cure time, taking advantage of the wet-on-wet window and saving the time to scuff sand the epoxy before the FF goes down?
