Good post Gary,

A subjective test while your plane is in primer, quickly rub your flat hand
fore and aft along the fuselage side.  Remember the sound,  That is wind
friction.  Now glue sample materials on the inside of the fuselage and
repeat the test.  You be the judge as to what you want to use.  The experts
have the science. Rely on their data. You fly the plane; you make the
choices.
