I'm making a shearwater sectional, and have a question about fiberglassing and epoxying the hull.  The instructions call for one layer of glass over the entire hull, but then an extra layer reinforcing the center strip, and a third layer along the keel at the far bow and stern.

The instructions seem to call for applying all three layers of glass, and then epoxying the whole thing.  But from my wrestling with fiberglassing the cockpit, it seems like I'd be far more likely to have a smooth surface if I applied epoxy to the first layer of fiberglass, then added the next strip, more epoxy, etc.  Is there a reason not to do that?
