Question for you Navy guys

They soak the area in epoxy and microfiller, then vacuum bag them. When the epoxy cures, they sand, fill, and recoat the piece.

Vacuum bagging is pretty common in cloth layup, but I've never heard of it being done with filler.

Microballoons in the epoxy. Fills in the gaps. It's not filler in the way that most people think of it.

Just enough to thicken the resin, then. I have heard of that before, although I never used it that way in any layups I have done.

But you probably don't also work with Radar Absorbent Material (RAM) on AS FREQUENT a basis as those folks. The material needs to be able to let through the frequencies they WANT to pass through but not others.
