As far as 'air dams' or strakes are concerned, they do not have to be
made of radar-reflecting material. The wing fences on the F102 were a
case in point. They were known to 'lie down' due to excessive spanwise
flow - the Deuce got a little edgy in yaw in low level turbulence at
high speed - 600+ - and every now and then after an air show one would
come back with the fences flat against the wing. They had no metal in
them AFIK, and were mostly some sort of honeycomb.

Hopefully lockmart is flying the crap out of AV19 and the F-22's structural
issues can be put behind them. That would leave the avionics and weapons
integration problems to work.
