 Also, blue foam is suppose to resist fuel

degradation-that's why we use it around the fuel tanks.

I think you are wrong about the blue foam Chuck. Easy to check.

The LE fuselage foam is dark blue PVC which is fuel proof, as
is the tan PVC that the tanks are made of.  The light blue
styrene foam that the wings are made of goes away quickly in
the presence of fuel.  We need to use the correct chemical
names for these foams hot just the (highly variable) color.
Density would be also useful in many cases for proper ID.
