Initially I applied Armour All to the contact surfaces allowing the two surfaces to slide against one another eliminating the Squeak.
Later I applied Frost King Rubber Foam Weatherseal 1-1/4" wide, 7/16" thick, purchased in a 10 foot roll at Lowes (#Black R516). Applied this in the gap between the Base Shield and Dash. This provided much more uniform contact surface between the Base Shield & Dash. This added contact surface also seems to stiffen the Base Shield resulting in much less flexing and no Squeaks.
