As some of you may remember, I removed and resurfaced my WAFs, and for that, I had to remove a few ribs from the wings and the stubwings (I have premolded wing skins, so the ribs are fairly accessible). I built two types of replacement ribs: the inner ones are made of thick (50mm) extruded polystyrene foam; the outer are made of thinner polystyrene foam (30mm), plus one layer of 2.8mm plywood.
I now want to seal the ribs with Micro, so as to make them more resistant during installation. Questions: - Must I sand the extruded polystyrene foam, or is the Micro going to stick to it as it is? - How can I glue the ribs back in place? Should I use Micro, or Flox, or anything else? Must I insert them as a tight fit, or leave a gap for the glue? Any ideas? Serge Vidal KR2 "Kilmanjaro Cloud" Paris, France
